I think it's likely easy to deal with right now...
First do an Admin Zone search for Guest.
It should show various language strings. Most of them come though one called GUEST I think, but there'll probably be some others that reference it within wider sentences.
forgot to mention that I did try changing just the 'Guest' string, but I didn't see any change, and it's not in the list of language strings that are pulled up when looking at a forum page with an anonymous post
Aahah! The system isn't showing the 'Guest' language string change on an existing post (even if I empty all related caches). It only shows 'Anonymous Member' if I make a new forum post
Thank you Chris for the tutorial and OCLE command. I want to keep the 'guest' usergroup name as it is so that it's distinguished from logged-in members who post anonymously. Therefore I've only applied the OCLE command, and we're in business. Thanks

That is what would be combined with BY_SIMPLE, to make the message you're seeing.
