UBB.threads PHP Forum Software Community Forums UBB.threads 7 Version 7 Support how do i stop mods from deleting threads in 7.3?

okay - testing 7.3.

in 7.2 i can stop mods from deleting whole threads and just allow them to move the threads to a hidden forum.

i can see no way of stopping this in 7.3

can someone let me know, how it is done, as previously they could delete a post, but not a whole thread.
