Ning, please allow us to charge membership fees to generate cash flow!

I just got an email from SocialGo that I really wish came from Ning.

They've rolled out a "Freemium" model. Networks Creators can have free AND premium memberships on their site. The NC can also pick and choose what content on the site is available to free members, and for premium!!

Does Ning plan to finally provide a way for us to make money? I think that its long overdue and hope to get a response to this
