Well,Just to let you people know,I had written this plugin for buddypress 1.0.X version and It works upto buddypress 1.0.3.I last tested it(on request of one of user) for buddypress 1.0.3+wpmu 2.8.4a and It was working.

So hopefully,It will solve your issue if you are using buddypress 1.0.3

But again,because of security reasons It is strongly recommended to upgrade to most recent version of wpmu+buddypress.
