Users shouldn't have to go in to each individual calendar item I create to be able to accept them. How can they even know they are there, unless I tediously send an email every time I add a calendar event?
Definitely a great idea - I've only just started using Calendar Events and to be honest I just assumed they would work this way, otherwise they're nowhere near as useful!
I was expecting them to have a 'Push to users' option, just like on Bookmarked reports.
