To the right is the demo of the Event Calendar...We've been working hard on this.  Hopefully it's close!

The Calendar instance on the left was created by the module (using version 03.03.08).  It is setup as a small calendar and only allows adding events and displays the month view only...also, it is setup to use the new "small" theme, does not display other month days in the view, and is setup to not display events in the month/calendar cells.  See the module settings for many other features!
