No matter what users do, I'd like all users on my WPMU site to automatically be registered on a specific sub-blog, possibly even a few sub-blogs.
Removing themselves manually after they login is ok, but ideally they start out with automatic contributor level access.
I've noticed some plugins that might help people register themselves on different sub-blogs, but this is not what I need.
To explain the situation a little more, I work for a school system which is using WPMU to host most of our district blogs. Some of these blogs are mandatory and all students need to be able to easily participate. Right now we are having to manually register students into these blogs, which is obviously not very efficient.
