UBB.threads PHP Forum Software Community Forums UBB.classic UBB.classic 6 Support Can You Close the Forums and Test Modifications?

You're correct - it ain't possible.

If you're playing with style templates, assign that template to an inactive forum (turned off but NOT private) and access it directly by URL (ultimatebb.cgi?ubb=forum&f=#).

You should be able to see the changes in that forum only, without affecting anyone else.
