In Pokemon-related terms, a section for conventions, cosplays, merchandise, and fan-made things is something that we're missing here, even though all that kinda falls on Pokemon General. These don't get mentioned too often, as I've seen new members in the past that wanted to talk about conventions and cosplays.
Yeah, while this might be nice, it seems the fanbase for that isn't large on PC because not many threads on those subjects pop up in PG. And if there doesn't seem to be a need for a new section, it won't get made. Because. Yeah :3
I don't know what forum I'd make. The Anime & Manga subsection to Culture and Media got made already and that might have been my suggestion ^^ I guess I'd still want a pokémon manga section but at the same time not since there's just not enough to talk about there without scans being allowed.
