I've submitted our organization application for this year.
Anyone interested in mentoring, please indicate your interest
https://code.djangoproject.com/wiki/SummerOfCode2017. Any experienced contributors are welcome to mentor. We also need project ideas on that page. I've copied the ideas from past years, but they may not be the best. If you have an idea in mind, feel free to start a new thread on this mailing list to see if others think it's suitable.
Any students interested in participating, the time to starting contributing is now! The chances of developing a successful proposal without any past contributions to Django is very low.
If you have a question, let me know.
