This is not so much support but a rather a general query but i guess maybe it is support?
I recently converted from vb 4.2 to phpbb 3.0 and then upgraded to 3.1.
I am now stuck with unnecessary groups and i need to know which ones are actual default groups that need to stay and which i can delete.
Can i delete everything in User defined groups without it causing conflicts? I know ill have to set permissions and all, just trying to weed out the bloat.
