This plugin is a modification of sidebar add user widget by DSader. It adds a whole bunch of control functionality that allows admin to change who is allowed to add themselves to a blog and also what type of permission is allowed. It also changes the way that the widget appears depending on the user’s status. It was developed primarily for course blogs.
Final, final update:
WordPress. org has started to show OLT some love and we are now rapidly publishing all of our plugins there. The new direct link to download sidebar add user widget is here and the plugin page is here.
Fixed the problem with the plugin not reloading user’s status when they first add themselves.
Just drop into the mu-plugins folder.
Any problems/suggestions just leave a comment
