They shouldn't be able to, unless some of the permissions got screwed up with the upgrade.

What makes you think they can?

I see why he's asking.

Bhuulo was a joined member, for some reason he didn't want an account anymore, so it was deleted. When that happens, there old posts show them as a guest. But they weren't guests in the guest sense. Real guests still can't post.

Is it possible to change the title of "Guest" to something else?

It will avoid confusion in the future.

You're not likely to see many more.

It can be done, but only if the forum is setup a special way. John could for example make a public forum, where guests could be able to post. It has something to do with permissions from within the Vbulletin Admin Control Panel for the forum (or rather catergory like VIP, News, Chillout room etc.)

We would be full of viagra ads in minutes, between all sites we ban hundreds of spammers every week that have registered never mind letting them post without registration
