[SoC] Mentors

[Giovanni Corriga]

Hi all,

since only five slots were allocated to us by Google, we have more
mentors than needed. Five of the mentors have been automatically
assigned when we selected the projects; this leaves nine more mentors
free.

I propose that we assign a second, backup mentor to each student, and
have the remaining four mentors be ready in case they're needed.

I invite you to reply to this message if you're interested to be the
second mentor for one the accepted students.
