I always find that setting meeting times is really inefficient. I would this simple solution:<p>I go to a web and say "request new event scheduler", which then simply gives me a url to share. Anyone who visits the url can add themselves to the calendar, add available times, etc.<p>The big point is to make it _dead_easy_ and _amazingly_fast_, making scheduling over email a total non-issue.
Build this Scheduling App, Please.
