JomSocial Group Blog and type of post questions

Please excuse me if this has been asked already. I tried searching first but can't seem to find the help I need.
I recently added the "JomSocial Group Blog" to my EasyBlog. I activated the feature (plug in) already.
1) My question is how do I go about only allowing group creator/moderator to create post for their group only?
also, I see when the EasyBlog user has the option to post site wide or group. But I don't want the average blogger to have access to post to a group categorie, or one group creator able to post to another group section?
Is this possible? Did I miss something is the settings, maybe the ACL,or some other setting?
I already have profile type set up so I was wondering if I over looked a setting?

If this option is not available will it be i the future? Or do I need to set some sort of approval for the groups?


2) My second question is how do I disable type of post (i,e video quote, photo..ec)
Id there a way to disable or hide these features?
My site is video based but everything needs to be handled trough Jomsocial; being i have a video approval and profile type extensions that need to control these feature.
So there is no need for the extra option in posting a new blog

Thanks for all the great support!
