Suggestion: Allow only admin to create groups.

Hi,

This is in reference to my post here https://premium.wpmudev.org/forums/topic/how-to-disallow-regular-users-from-creating-a-group

Andrew suggested I post it here.

I would like to disallow everyone from having the ability to create groups? I only want certain people to be able to create groups such as moderators or admins only.

Thx!
