I've arranged for MediaWiki to get some interns this spring. Four bright college students -- they already know web development and have had internships at Facebook, Google, and Microsoft -- need a mentor.

It's a bit like Google Summer of Code, but a part-time team rather than one full-timer. They'll each be working on MediaWiki 8-10 hours per week between now and the end of April. I figure I need one experienced MediaWiki developer as a mentor -- I'll be your admin, and community dev Amgine will be your backup. Amgine will lead the students in person next weekend during a code sprint in Vancouver.
These interns don't yet know what they want to work on so you can choose a project with them. I'd help you run two half-hour IRC meetings per week and we'd run them through two-week iterations between now and the end of April. I figure it'd be about 5 hours a week, possibly more at the start as we ramp the students up.
Please let me know as soon as possible, preferably today or Monday. I'd prefer that the students work on something that will be deployed on Wikimedia sites.
