Sorry if this isn't very relevant, but I joined the RA2 community wayyy back then... I'd like to estimate 2003 or 2004. By the way, my usernames were probably Dr Doughnut and Gerbilfyed, and I was an annoyingass 10 year old who just discovered internet forums at the time :P. Those forum bans were justly deserved :P
Anyways, I'm amazed that this community is STILL alive and active, and I'm glad there is a section for combat robots that still shows the sport, more or less, is still alive in some manner.
Robot combat has been a large driving factor in who I am today. I first got into Robot Wars when I was 3 or so, and that sparked my interest in robotics. Middle school, I became an active member of my robotics club, in Highschool, I lead my robotics team to victory and strengthened my interest in Engineering, and now I am about to be a sophomore (junior if by credit hours) at Texas A&M University for Computer Engineering, and I am still set on robotics. I've also been building a Gundam cosplay which has near completion. (

But yea, I'm surprised but glad that the community from an obscure game from 2003 is still alive and well.
EDIT: ACAMS has the same avatar hes always had since I first remember him
