I think I have formulated the easiest way to acheive this. I think I amgoing to set up two seperate calendars... One for public posted events and one for organizational events.. takes care of permissions, the modified form and the categories... I can then make changes later to one group without impacting the other..

Cheers,
Gregg

To achieve this I should just be able to modify the table names in the sql/mysql.sql file and then all the calls to it in the php. Here goes nothing.
