Some of the responsibilities as I see them:
- admins are backup mentors - if there are a lot of mentors, then the
admins never have to step in but it is always possible that admins may
be asked to mentor. This is why it is important to have systems in
place (e.g. the student wiki page like Renata[1]) that allow admins to
get their head around a project really quickly
- helping to attract mentors
- getting to know the rules or know how to find documentation about
rules (e.g. Google's FAQ, rules change from time to time and mentors
don't always realize)
- maintaining the wiki and other tools
- ensuring evaluations are completed at all deadlines
