Hi i am searching for a way to enable members to show when they can meet up.

every (group)member should be able to maintain a personal calendar and fill in on what days he/she is available to meet.

the results of all the members in a group should show in one group calendar when everyone is available to meet up.

I have purchased a few of the calendar tools from the marketplace but i wasn't able to create personal calendars and grab the results to one main calendar.

i hope someone has a good idea on a approach.
