Moderating threads in certain forum by usergroup

[محروم.كوم]

I have one forum where I'd like to have all new threads moderated, except those made by a certain usergroup. I would like all members to be able to make posts, but only this one usergroup to be able to start new threads.

Currently I have that forum set to moderate all new threads.
Admin CP -> Forums & Moderators -> Forum Manager -> Edit Forum -> Moderate Threads -> Yes


But this moderates new threads for all usergroups. How do I set a specific usergroup to not be moderated?

Thanks! __DEFINE_LIKE_SHARE__
