EDIT EVENTS CALENDAR

ADDING CATEGORIES
2/5/13 I have updated the All Events page to include Membership Events. 
What I did was to view the page, click "Edit this" at the bottom, 
then add another Custom Field of "Category" with value "Membership Events". 
You're welcome to do this for any additional categories of events that should appear here. -Mark 
DELETING CATEGORIES
From an admin page, click "Posts" on the upper left, then "Categories" below that.  This will list the current categories which you can then edit or delete.
