Is there a way to remove all of the sites that are greyed out, not in use anymore? It keeps telling me they are still in use in some places and can't be deleted. During the initial setup, it wasn't done properly and now have hundreds to look at. They are also showing up when I'm trying to exclude certain groups from the chat feature, and am not able to select the correct group as the selection list is too smail. Any ideas would be helpful.
