I gotta disagree on the 5 members screenshot change. It gives us a look into their friends list to see what type of people they have added (Possible spy, etc).
IRC screenshot - Staff PM seems sufficient.
As for mentors.. it could get a huge load of their backs if some applicants didn't need a mentor. :s
Graduation
Date of acceptance seems good.
Event Tracker - Agreed.
10 members - Disagree: Same as the previous one with the 5 member screenshot.
Teamspeak - Agreed.
Gotta wait for other council to post or else I would go ahead and make changes myself.
