I moved your post here so we can discuss the new feature - let's leave the Kabissa Community Calendar topic itself clean, without replies.
The general idea over the years has been to use Google Calendar to schedule events and deadlines in the Kabissa calendar, and then to display that on the website at http://kabissa.org/calendar. It can then also be subscribed which is very handy indeed.
Now that we can embed calendars in forum topics, we can display the calendar directly here on the forum as well!
If you want to add things to the calendar, post about it and let me know and I will add it. Going forward, this would be an editor or moderator task for @meredithkabisa, @ted or other new recruits.
