Ohh I figured that out... The problem or thing that needs adding is... When you "Create" a forum. You should add a Radio Button on "Is this forum a Calendar?" If yes it does the Y and no it does the N... Just my 2 cents...
Also a bug... I put in an event. Then I went to delete it and it gave me some weird error (cant remember it) and the stats for the forum still show the message being there but it isn't... Any suggestions...
