Online Schedule Planner

[ZIMdudeAlchemist]

This is something that the guys at ScrewAttack are doing with their ScrewAttack Gaming Convention site, you post up the schedule of events on the Fanime site, and users can add a certain event into their own schedule. Plus, they can print out their personal schedules so they can use it for the duration of the convention instead of wasting time scrolling through and picking which ones to go.
