I think there are 2 Calendars that really should be one ...

If you go to "Groups" Then let say choose the Dallas RPG the calendar there will show the following event on the 23rd:

But if instead you go to "Forums" -"Social Group Forums" -> Dallas RPG and then "Events" it won't show anything.

One is called Social Groups Calendar and the Other One is Community Calendar ...

IMHO they ought to be the same one ..
