WordPress MU

Before I built a solution, I was wondering if there was a plugin that allowed me charge for storage upgrades to my Wordpress MU members. So the default 10MB would be free, but if they wanted to add storage, they would pay a one-time fee to upgrade to more storage.

I would like to integrate it with PayPal Direct Payment API, so the user never has to leave my site.

I would assume that the plugin would charge their card, and then update the database table for whatever blog the user chose, and add the additional space to their blog automatically.

It's one of the plugins they offer.

Thanks for the quick response and link. While I've checked the site out before, I've never browsed around the member section. Looks like it's time to start.
