Yea, man, i'm not really sure when Millard got there. Was he the original owner of the site, or did he buy/acquire it from somebody else?
Meso was a pretty cool forum in the 90's, mainly because of it's older writers/articles from guys like Lyle McDonald, et al. I was there around '96'ish, IIRC. There was aguy there named FLEX, who was probably the most popular at the time. I didn't know him that well though. EF started right around the same time, again, it could have been between 95-96 for both these forums, I know 96 for sure because I still have links from there that year, both myself and others. The forums really blew up after MM2K talked about the forums in one of their issues, I think a Q&A from Bill Phillips, where he mentioned that he didn't go to them because of the hate there was on them. I had already been on them right before that, as i was going to the Junior College I was at and posting from those pc's in 95. MFW was the most popular, it was brutal as fukk though. I was just an 18/19 year old kid, and the drama wasn't bad for me because I was able to read posts from all the guys in the magazines, and I was also too scared to post and get roasted by them, lol. So I just read a lot. I know that right after that, I did a search....fukk, what was that old search engine back in the 90's??? I did a search about bodybuilding forums, and Meso and EF popped up as actual 'forums.' There were other forums like Donovan Brown, who actually got busted after posting too much stuff up. I logged into Meso first, but right after signed up at EF. EF was more busy, so I stayed there.
Around December 96, Llewellyn and Brian Raupp opened up the site Anabolix. They had a falling out, and then Brian created Anabolex, while Bill kept Anabolix, and think that is how Anabolic got started. Both were sister forums to EF. I think it was Llewellyn and Kneller, i'd have to go back and verify this though, that were partners in the supplement company, Mass Quantities. They had a falling out, and I think that is when Paul (aka George Spellwin) bought the company, or something along those lines. Brian also started selling his own Synthol, I think he just used MCT Oil.
Once those forums got more and more popular, I didn't go to Meso much.
Around 97, Underground Supplements was started by Superior1. It was the forum that had TAZ on it. I went there a lot, but I am not sure I posted much on it. They started doing newsletters similar to what Hulkster did at EF, etc.
In I think '97, Paul started EFS, and the board slowed some because all the vet/popular/known posters just posted there mostly. Duchaine did not post openly as much at EF because somebody mentioned his handle name openly, I think it was a guy named gymrat.
There were other forums too like BigSport, Renagade started i think in '98, and a few others. In 1999, EF was shut down for a while because of hackers. It restarted at the end of 99, or maybe the beginning of 2000. I had taken a break from the forums between 98-the end of 1999 because of college, and just notn having easy access to internet 'dial-up' access, lol. I think I went to the library a few times, but it was always super busy at my college. I came back and got back on EF, but didn't post for many months because it was all a new crowd in 2000, and almost all of the old crew had left. It was insane. That said, this started a new generation of posters. Post-2000, it was insane with all the forums that popped up, for like 8-10 years, though some went down after ORD, and especially now since social media came about.
Rawdeal and others will know more about TSC and SA. I may be getting them mixed up, but around the mid-2000's (2006/7?), I think is when one of them was created because I remember that loon needtogetas mentioning he was going there, along with a bunch of others he was friends with, which was an automatic turnoff for me. I was banned in 2007 from EF, I think from BRR or MrX, I can't remember. I was never a member at TSC, but looked through it as a non-member toward the end of it. I mainly just knew of Zeus and Big White/UXL, who were members here, and a few others places I was at.
