For me it was TWL (The Wrestling Lounge), which I found in Feb or March 2008 via Yahoo! Answers. Wbu?

XWA (Xtreme Wrestling Association) which was a match writing fed. I found it in 2009 and had my first e-fed character there. Also got my brother to join at one point but it was too much for him lol. It's closed now but they still have a forum for wrestling discussion which I have an account on and check every once in a while.

Something really generic like United World Wrestling Federation.  Back in 2001, it was really basic, just a bulletin board with IC and OOC stuff completely mixed together.  All the RPs were threads and replied back and forth setting up matches.  The fed runners used an old random match generator, so the matches ended up making very little sense.  The characters were also completely ridiculous, with X-men clones, faux vampires, steroid beach bums, and some ancient Mesopotamian god.  But it was good silly fun for me and a few friends back in the day.

My first one was something like Pro Wrestling Secrets Revealed Federation, for a website called Pro Wrestling Secrets Revealed (it was just some Facebook-esque website). It lasted maybe three weeks. I cringe when I think about some of my very first promos....

Technically my first fed was... uhh I don't remember the name but it was owned by Gage Smith. It was November 2009, but it never got off the ground.

In April/May of 2010 I joined a fed called EIE (Extreme Impact Entertainment) on Y!A and I guess that would be considered my first official fed.

I had no idea what an e-fed was until Tre found my tumblr and dragged me here to drink the kool-aid for the first time.

Wan't exactly like an E - Fed, but UCD (before it up and went fucking under), was mine for a few years. Sites (and all muh work) is gone. RIP. 

But now I'm here so I'm pretty okay

Technically it was called YHWA on Yahoo! Answers Wrestling section in August 2009. My character ambushed someone in the fourth episode. I made my first ever promo for the fifth episode but the result never got posted :/

Then I got an email from Straight Edge Punk asking me to join his E-Fed. It was called YWPL and again, it was on Yahoo! Answer Wrestling section. I'd consider YWPL as my first official E-Fed, lol.

Technically Shootclub Wrestling Alliance which was the first e-fed I'd heard of and it was kind of impressive in it's scale and charged for membership after you got out of 'Shoot Camp'.  I did not.  I filled a form, but never promoed.  Then I learned you can do this shit for free and I joined an endless stream of fly by nights with real wrestler characters instead of CAW's via connections in (dating myself) AOL message boards.  One guy had to have opened like 20 in a year.  He just kept opening and closing and inviting me back.  Among the characters I played were Jeff Jarrett, both of the Outsiders, Ric Flair, and Goldust, some all at once, occasionally taking up half of the meager roster.  My first character character was a guy named Sam Hain whom I used Raven as a picbase for and can be linked to all of my characters in one way or the other (mostly via the cult that endlessly spawns Fertility Lynch's)

First ever E-fed I was on was one I ran and operated myself.
It was called the Raw is War Wrestling Federation. It was forum based and back then it was a family owned company. The boss was the father of my character (Who I mention here sometimes as Ryan's mentor Prime) and he had a few brothers that he fought with and against. That was back in 1999... Yeah I'm old lol.

Black Wall Street. It was ran by Twillz and Snagz. I later went on to join EHW. I was then recruited to EAW after that by Jaywalker and Mak.

My first fed was  the international wrestling alliance (IWA). Very short lived fed that had a cool gimick of being an NWA like overseer of about a half dozen regional territories that merged them all into a global company.  The schedule was very light (the only requirement was 1 Promo and shows were scheduled every 2 weeks). I remember debuting the Mark Michaels character There and on our first show winning a 6 man scramble match.

My first fed was a place called Brutally Extreme Entertainment back in 2008. The founder had a Ruckus picbase. I ran a black wrestling family consisting of four brothers using Booker T, MVP, Shelton Benjamin, and Elijah Burke as my picbases. I helped write matches too.

Before that I co-ran a console fed called No Mercy Wrestling (formerly Attitude wrestling). Our crew went as far back as War Zone for PS1 and we were prominent during the No Mercy days. The last game we ran our promotion with was Smackdown Here Comes the Pain.

EAW Trueborn

I think it was either AWE or DCW, it was kind of them both or something, but it was ran by a guy named TRDD whom I met on Y!A. I think he just messaged me and I checked it out and we spoke on Xat. And I remember meeting people like Hades the Hellraiser (we started at the same time, crazy), Sasha Fierce, Infamous Anderson, Doni, Suicidal D, Dorin, and even Dark Demon. Back then, I was aware of people like HBG, Cameron, Mr. Blood, DEDEDE's name came up sometime, MK Beast?... Y2Impact, and then it merged with DRW, an efed ran by Demon where I did win a world championship in the debut show, but the website got erased like 5 mins after it was posted because I think the Blood guy was annoyed or pissed off at Demon or something. Really not that surprising, lol. But people were petty back then. I was still the Moongoose McQueen gimmick, running the WCW Jericho/ Rockstar persona, that is still somewhat relevent in my character today, but ... weirder.

Universal Wrestling Federation (UWF).  It actually started in a forum I was a part of.

A place called XWS back in late 07. Place tried to be overly extreme every week, cunts would basically die and then kill other cunts. There was always drama over things being unrealistic...despite everything being unrealistic. Place died, spawned another, it had a fork, two places fought constantly trying to out do each other, led to one owner jumping ship shutting down his fed in the process; one that survived still died quickly.

Fun times.

Proving Ground Wrestling in 09 was the first E-Fed I joined after XWS and the first time I built the O'Hara character. UWF (same as Shaker) wasn't long after as well as a few others in that circle.
