here's my story:
been there, done that 
nah, it's way to much to write down and I cannot believe anyone would be interested in that.
But: topic starter should kick off his own thread, so let's hear yours!
Damn...
My story starts somewhere between 1997 and 1998 on Diablo 1 Battle.net. I used to play there together with my neighbour, our bills were huuuuuge

I was playing warrior and took a part in probably the biggest clanwar in d1 history: True Heroes vs Hell Warriors, hundreds of players in both clans, thousands of ears

With the beggining of d2 i finally had righteous internet and was ready to roll on CBN right from the start. Many clans, many tournaments on BNPL, D2CL and EP too during 2000-2003 years.
Autumn 2003 changed it all. 1.10 patch made huge impact on polish pvp scene. Most of us moved to private pvp realm - Angrenost. Realm still exists, but we will be closing it soon, due to Diablo 3 release. Some of us were playing there for ~8 years, so was i, later becoming an admin and succesfully participating in many tournaments.
I also came back on CBN after few months ( autumn 2004 probably ), just on time to see beggining of Polish Clan League, i joined in with few of my Angrenost friends and so the CBN saga started once more

I became an referee and admin there too, won some tours, wrote a decent guide for barbarian and quit playing somewhere in 2009.
Through all this time i was also an active member of polish-hc scene, played on EP and GM rules too, especially in old days, 2004-2006

Right now im looking forward to May 15th, together with my clan m8 from Hell Warriors (
