I'm a full blown Wikisourceror. On the multi-lingual Wikisource I'm an admin, and I'm a bureaucrat at the English sub-domain. Mainly on Wikipedia--when I wander over to this neck of the woods--I add links from the encyclopedic articles about authors or works to the corresponding Wikisource pages. Occasionaly I'll copyedit pages as I read articles for fun and find grammatical/typographical errors and whatnot.
Of course, if anyone wants to get a hold of me, dropping me a line at my Wikisource talk page is the best way of contacting me. Just, please mention you're from WP, so I know how to respond.
