Jomsocial Custom Project/Hack

I require a modification of the Jomsocial component (version 1.8.7) running on a joomla 1.5 site. My site heavily depends on the privacy of groups within Jomsocial. Currently in groups, users can post on the group wall and also create discussions. I need to add a moderation feature on the wall and discussion board. Basically, when a group member (who is not an administrator) can post on the wall and discussion board, but the posts are not published until approved by a group administrator. The group administrator is notified that a post has been made (either through jomsocial or e-mail, which ever is easier). The administrator can then view the post and either remove it, or publish it. Please note that one group can have multiple administrators. Also note that a group administrator is often not a site administrator. This is already built into jomsocial. It would also be helpful if the administrator could see where the post has made (which group, wall post or discussion name) so that they can go and review it. Also, currently all group members can start discussions, please remove this feature for group users, only allow this for group administrators. ## Deliverables I have a test server which can be used for developement.
