Welcome to my Codex User Page. Please pardon the mess; I'm familiarizing myself with editing and writing documents for the Codex.

I'm above average at reading PHP code and figuring out what it does, so I'd like to eventually create documentation for the functions that haven't been written up yet. I'm also pretty good at proofreading, so I'll most likely start with fixing minor errors/typographical errors first.
I think I answered the first part of this question in the previous section. Oh, well. As for the community, I've been responding to threads in the Support Forum for several months now, and helped people resolve their issues on a case by case basis.
I can't answer this without potentially straying into "self-promotion," so I'll let you know if I think of anything another time.
