adding new usergroup with set of existing permissions?
 

Guys,

I'm confused!

When I create a new usergroup at the top I have 2 options:

Create Usergroup Based off of Usergroup:
Create Forum Permissions Based off of Usergroup:

Whats the difference between the two of them? I cant see what the forum permissions based one does and I would expect it to be the same as the first!

Many thanks in advance.
