Biophysical Society members work on a WikiProject Biophysics, run a wiki-edit contest yearly, and have a wiki-oriented session at the annual meeting (~7000 total attendees, 1/3 international).  This year the meeting is in SF Feb 15-19.  The wiki session is on Sun Feb 16 2:15-3:30pm.  The theme of both the session and this year's contest is open-license media and their importance for science.  The chair is Jane Richardson, past president of the society, WikiProject Biophysics and User:Dcrjsr, and the guest speaker is Daniel Mietchen from the Museum fur Naturkunde in Berlin, WikiProject Open Access and User:Daniel Mietchen.  The editing focus will be uploading images to Commons from David Goodsell's "Molecule of the Month" features (http://www.rcsb.org/pdb/101/motm_archive.do), just last week given CC-BY-3.0 license.
If you're a student wiki-editor in the Bay area with an interest in science, you might like to attend the wiki session and the meeting in general.  For a student, the cost would be $25 for BPS membership and $80 on-site registration for the entire meeting.  On Sunday there's the New & Notable session and a symposium honoring the International Year of Crystallography, and on Monday there's the Awards session and the National Lecture.  You'd also be very welcome to chat with last year's contest winners (one from SF) and others at a Sun dinner.  Find the BPS meeting info & program at http://www.biophysics.org.
