I was trying to change some permissions for guests on my forum when I realized there is no unregistered or unconfirmed user group. My forum was imported from a vBulletin installation, and I can't remember if there ever was a usergroup for guests after the import. I don't think there was. Is there any way to import them or otherwise fix this so I can change permissions for guests?
Here's what my group permission page looks like:
and I believe it should look like this?
