2. AMP review Community website to organize meeting Group management User calendar management Automatic meeting time Suggestion of meeting location Focus on study groups but group and meeting time functions are also useful for students’ clubs, sports activities… Gain of time, best solution to satisfy more people 2011-04-202CS408 Computer Science Project - Team JVA

3. Feedback Availability: make it as easy as possible to update timetable Import from Google Calendar and OTL Remote e-mail update Meeting time algorithm: more precise constraints Weighted time Limited time range(no meeting possible at 4 a.m.!) New features Suggestion of meeting location Vote for meeting time 2011-04-203CS408 Computer Science Project - Team JVA
