Something is buggin me, I think I just found a mispelled phrase, here:
./mybb/admin/index.php?module=user-groups&action=edit&gid=4 (Any GID)

"Along with the settings above, you can this group's global settings for Post Reputation."

Maybe my English is limited, but I think there is some word missing between "can" and "this".

Thanks for the head's up Sama34; I'll check it out!

Glad to hear it! And don't know if already said it, but MyNetwork rules!
