As for me, I became a fan of the series in February 2011 (though I did watch a little of the 2003 anime back in 2004 on Toonami). That means I've been a fan for almost 2 years now.
Also, yes, Atom is cute. I'll leave you fangirls to love on him though.

Since I've joined, activity seems to have fluctuated over time. When I first joined, there was actually quite a bit of activity. However, the forum was pretty much dead for the first half of 2012. As you said though, the forum seems to have been gaining more activity recently.
It varies from time to time.
