Part of the Serebii/BMGf peeps that left the place. Honestly, Serebii is actually my first forum, so I grew accustomed to that place and not too much towards PC back at 2008-2009. BMGf too, but after a short while lurking around, I don't really like the community, so I left pretty quickly. Eventually, I left Serebii at the middle of 2010 for a short while, and even left all the forums I've frequent altogether in favor of deviantArt haha, only coming back once in a while to lurk.
Serebii isn't all too bad... if you ignore all the Pokemon discussions and the misc chat threads haha. I swear, the only two things that kept me alive on Serebii back when I returned at the end of 2013 are the Shiny hunting discussion thread over there (since people are doing Badge Quests and it's interesting to see them complete them, while over here I can't find anyone posting haha) and the Fan Clubs, and even there I wasn't so active. Something else might be the weekly spriting contests and the advent calendar threads, but yeah, that's about it. Sure, I met a few good folks, but I'm still not comfortable with the community as a whole. Like people said, it's too strict.
While BMGf... huh, too quiet for my tastes. Even after returning after about 5 years of hiatus, it's still dead to me.
I also used to post around Arkeis forums, pretty sure most of you at least know Arkeis.com, and that was the forums haha. Yeah, an independent invisionfree forum. I was friends with most of the current staff and h-staff, even from way back when they weren't staff yet and aragornbird was the only admin. It died some time last year, which happened after about 2-3 years of me not coming back there lol. I wish I had added any of the staff's contacts back then though, they were fun people. :(
