All people involved in the Eclipse community should post their ideas here. It’s a good time to start posting ideas, as students will start looking at mentoring organizations in mid March.
There is little downside in participating in this program in my opinion. As an Eclipse.org GSOC mentor, you get the rewarding opportunity to mentor a student in the ways of Eclipse and open source. As a student, you get Eclipse experience and paid for your contributions!
In the end, the whole open source community benefits.
