I'm only really active here, but I ocassionally post on
DS-Scene (been posting here more lately)
RPGFan forums
And another forum I can't mention here because it contains roms of certain old RPGs.
Oh and I lurk NeoGAF while I wait for my account to get approved.
EDIT: I totally forgot, probably since these two aren't forums per se, but sometimes I comment on Andriasang and Siliconera's articles/news posts.
