waitwaitwaitwaitwait it's today? I thought it was the 27th.
Anyway, first server I played was "Kom's Server Thing =o". I was promptly banned by an admin for "having a high id". I can't remember the admin's name for sure, but I know it wasn't Kom himself.
As for join date, I believe Demo was v9, and buying the game was late v10 / early v11.
First map I played was the Slopes.
