I would like to use the adding of new users to a default main blog feature. Not for BBPress or BuddyPress reasons (this is no longer needed with BP 1.5 and BBPress 2.0) but to enable post "broadcasting" from one blog to another. That means all users within my network should have author access to blog ID 1.
I'm getting unwanted permissions behavior though. If an existing admin of blog ID 1 creates a new site, this plugin will bump them from an admin down to an author. Could the developer add a check to see if the user in question is already a member of blog ID 1, and have no affect on their role if they are?
