Shared Object Cork Board

Maybe this is just a simple question of tools.

I’m trying to create a bulletin board for use on our company intranet as a collaboration/notes area between members of our dept.

Do you need Flash Media Server in order for this to work?

If not, how can I make it so that an object I add to the screen will stay on there until it is removed, despite browser refreshes and closings? Also, objects placed on the screen should be viewable by anyone that is on the site.

Can this be done without FMS? (I’m not even really sure what FMS does or is exactly)

Thanks in advance…
