Help with Invites Plug-in

Hello.

I need some help with Invites Plug-in, where user can send emails to friends promoting his blog.

Is there a way to make certain features available only to Supporters?

and How do I place Invites plug-in menu at the top 'Dashboards' tab in the Admin page and rename it to 'Promote my blog' just like Edublogs?

Thanks for your help.
