Portal Group Membership Accept

[TroyBum72]

I would like to recommend that users be allowed to accept membership invitations to groups from the "home" notifications window, instead of just getting a notice(that needs to be cleared manually), having to browse to the Groups page, click on the hyperlink for invitations, then accept the invitation.  It seems like the workflow could be simplified.  It would even be neat if that acceptance would clear the notification, like it does when accepted from the group page.
