I'm an admin, if you're looking for one of those (mops up vandalism, does housekeeping, etc). I'm a 'crat if you're looking for one of those, too (deals with username change reqs). I'm also an accredited reporter, which means the community feels it trusts me with an @Wikinewsie.org email address and access to any embargoed material we may be handling.
My aim of late is to try and produce quality original material. A speciality I'm developing there involves interviewing academics about their research. Within the sciences, biology, mental health, and marine science are my things; other interests are aviation, disasters and accidents (including their prevention), and crime. Some of these are also capable of being interlinked.
