If you're a prospective student, or other newcomer, take a look at our gsoc-2015-ideas page and think about what you'd like to do for the summer. Don't be shy about suggesting your own projects, too; we are always happy to discuss project ideas related to the Plan 9 family of technologies. You should also probably sign up for 9fans, our main mailing list, if you aren't already on it. You can also check out our GSoC Student Application template and our GSoC Student Expectations.
The entire community is encouraged to contribute good summer-sized ideas to the gsoc-2015-ideas page. This will be a useful starting point for future years.
Anyone who wants to follow along in all the GSoC fun is invited to join our Google Group. We do a lot of planning and discussion of the program there, and that's where all the regular student and mentor reports will go (with consolidated summaries sent to 9fans).
If you're a prospective mentor and you're not on our mentor's mailing list, contact Anthony Sorace (a@9srv.net).
To make sure everyone's on the same page going in, we've tried to make our expectations on various parties explicit. To that end, we have pages for GSoC Student Expectations, GSoC Mentor Expectations, and GSoC Admin Expectations.
