Oh well, for the GPSL I could try- what I don't like about communities is a) the drama- which ALWAYS happens b) having to write with characters from Supernatural, or other shows I know nothing about and the like. But a GPSL is like a PSL but with more people xD If it's smallish I would actually love something like that. Facebook updates and tweets- Instagram pics and the like?
I can't promise it'll work out, but for a Glee PSL I'd give it a really good try! :) I thought you meant a community in where you had a ton of fandoms... Heh
And sure, let me know about the PSL ;) I'm around always, so yes. Whenever you want!
