collapse forums in the "forums and moderators" "modify" page
Ok,
I have now entered the license number. Hoping you are satisied now with this

My problem ist the following:
I have about 500-1000 forums, don't know exactly how much.
Many of them aren't in use yet.

But our problem ist, it takes about to 6 minutes with dsl loading the "forums and moderators" "modify" page.

What can I do about this?
Is there a way to personate the forums like it is manged with the templates, meaning they are king of collapse and you can expand certain areas ??

Otherwise I will not be able to go to this area of the control panel anymore very soon.
