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 Wikicommons--when I wander over to this project--I want to add audio files of spoken texts to help supplement texts existing on Wikisource. Occasionaly I'll also do some maintenance work, but mostly I'll be interested in adding the audio files.
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 Commons, so I know how to respond.
