I changed the link at the bottom of the Calendar Sidebar to link to the
Popup Calendar that has existed for awhile but that few people knew about.
I use it to add in my personal meetings, events, and appointments. if it is an event i don't want anyone to see but me, i just mark it private. i also use it to mark things i want done by a certain day.
Private events can only be seen by you, members only by members, and public by everyone. You can add items via the members screen, or by clicking on the date on the popup calendar (members only, of course).
Please let me know if you have any questions, suggestions or comments about the calendar system in general, or the popup calendar in particular.
