UBB.Developers Forums UBB.threads 7 Development How Do I? A Few Easy Questions

First of all I would like no anonymous posting. Where is the variable that requires someone to register before being able to post?

Also within a post there is a label after the name letting people know how many posts they've done I assume. For my first couple of posts it has said "stranger." Where do I edit these names and also I am seeing the name and then a space before the closing parentheses like this:

(stranger )

I'd like to fix that to the following:

(stranger)

Also where can I set the default for the preview a post variable to on so that it is checked?

Thanks, any help is appreciated.
