I know screenshots / dates / name drops would be really helpful. Unfortunately I have no screenshots. Dates are also difficult. It was a LONG time ago, and what's worse is that what feels like 3 months back then may have been only 1 month. I try to be conscious of that fact when I write "several months later" but I wouldn't be surprised at all that if you try to add up my timeline it doesn't work out. There are, however, a couple of solid dates I can point to. I don't know what the date is, but it's probably Googleable when clans were enabled on WC3, and that would give you a timeline for when SGOD and Behh were created. I'm not sure of the first westy clan. The two oldies that come to my mind right now are fr0z and wudi, but I'm unsure if those were just super old or were created on the very first day. If Rival comes back I'm sure he could share A LOT of history on West.
Everything I've written to this point was before TFT came out. I'm going to attempt to drop TFT coming into play, but that's actually difficult for me to do because it had virtually 0 effect on East for a long time.
Name dropping is also inherently hard. Not only was it a very long time ago, but everyone starts out an unimportant noob who wouldn't be on my radar. By the time they were on my radar, it would be difficult to say if they started 3 months ago or 2 years ago. People also tend to have a big bias towards making themselves out to be more oldschool than they actually are. It was almost laughable how many people in 2010 talked about the game in 2004, when there was 0 chance they played before 2006. We might be able to get a date on when a couple maps came out which would be helpful. And of course, I have a solid date for when StH was created, but silly you thinking that's the next clan to get mentioned here ^_^
Some revisions (I'll clean all it up when I'm finished, but for those who already read the first posts): A notable person I forgot was LordBlueBalls. LBB was an SGODer and shaman of hcs. He was by far the most inactive of the shams, and basically quit for a while soon after I started. He did come back though, but even though he was rusty, Pigger/2nd wouldn't dare diss him due to SGOD status. I got along with LBB, but that might have been because by the time he knew me I was already decent. He's definitely of the same cloth as Pigger and 2nd are.
Also I got SGOD mixed up with XROC (the OG ladder clan) at some point. And it censored out hcs, which stood for h@rdc0re sheep.
