[NOTE: this message is probably a duplicate of a previous post where I forget to include the Image I intended to attach] I have developed a number of what might be called ghost groups. Some (most) are as the result of removing groups behind gnus back. Others, I'm not sure of their origin. These groups now appear in gnus -> groups buffer with an asterisk before them as in the included image below. They do not respond to simple C-k nor do they respond to C-u G del How can I get rid of them?
