Not only are there many discussions in the main Forum but most of the 69 groups have Discussion Forums of their own. Fore instance the SW Education Forum group is very active. We use this group to document the activities we are involved in fighting to improve our schools. The Events calendar on the main page is Shared by everyone and it displays the next six events in the queue. You can, of course, also start a discussion about a special event you are organizing and invite input.
