I'm setting up a member-based site where we want to give users the ability to add their own blog to our Autoblog plugin.
For example, Bob (who just joined the site and paid for his Membership) is now a premium user. I want to give him the ability to connect a blog or two to our site's main feed using Autoblog. We will be scaling up the site in a few months and don't want to deal with thousands of updates a year, instead, we want to let people use Autoblog on their own.
Oh... while we love Bob, we don't want to make him – and all his fellow pro-users – Admins.
