BuddyPress.org

I wish to be able to assign specific subscribers write privileges to specific pages in my CMS WP/BP website. I tried Role Scoper, but it crashed my website. I presently have the following plug-ins installed:
BuddyPress
BP Group Management
BP Profile Search
BP Group Email Subscription
BP Profile Privacy Mod EW
BP Registration Groups
BP Restrict Group Creation

Will one of these, or some other BP plug-in provide asssignment of privlieges by pages?

Thanks,

Airpilot
