User Permissions

Hi!
Am using civicspace-0.8.5

I have the authenticated users posts (blog and comment entry)set for mandatory moderation que for approval of site staff approval.

I wist to have a new group that can over ride this restriction .... ie : to post freely (un-moderated).

It appears that only the adm node gets to override this restriction. I dont want this new un-moderated group to have all the control of the administrator node ....... nedds the just be able to post in thier blogs and comment freely with-out approval delay.

Can this be done?

Thanks!
