Supporter Levels

Hi there,

we are setting up a new MU Site and are using supporter and Membership. We want members to sign up for 1 of three options: Trial for 30 days = blog with subdomain, plugins, themes and limited space; silver = blog with subdomain, plugins, themes and limited space; Gold = option sub or own domain; premium plugins, premium themes, large space.

There shall be no sign up for a free blog. We are using edublogs.org as example.

How can we creat this in supporter? Any help urgently appreciated.

Thanks alot
