four imho crutial functions

[anonjum]

• sign out must be possible (upper left corner, wherever)
• deregister from event must be possible somewhere (user feels trapped otherwise)
• set up my own event must be possible
• need to see more then three events if they exist -> implement interface with more then one row of events. (cant accept invite for event if i already attend four events)

Please don't create duplicate issues or issues that cover multiple unrelated points
