I've tried the above but the Shout Box still shows on the login/welcome page. How can I turn it off?

Thanks,

Control Panel » Group Management »
Select Site Permissions for Guests
Set Can see the shoutbox to 0
In fact you might as well set all of the fields to 0 on that screen.

Thanks for the quick reply.

Interesting. We are on V7 of UBB and when I click Group Management, there are 2 tabs, Group Editor and Group Access. I don't see a Site Permissions option.

Also, the group "Guests" is not in the list of groups in the Group Editor tab but it is in the Group Access tab. If I click the Group Access tab, I have set Access Permissions to No Access for the Guests.

Can you point out what I'm missing?

I can only say that you must have a version older than 7.3.
I skipped from classic 6 to threads 7.3. and now I am on 7.4.1
See if you have a option Control Panel » Permissions » Site Permissions.
It may be there.

We are - V7.0. There isn't a Permissions link.

WIll keep digging and trying to figure it out.

Thanks again.

Please add the url to your forum in your profile.
Sometimes it helps when someone wants to try to assist.

Just added it.

Thanks for the suggestion.

The new permission matrix was added in 7.3; hence why you don't see it, as you're running a very buggy old build
