why dont they let you put forum in your title instead of registered user?

I’m not sure what you are asking? Can you please clarify your question?

^ its supposed to say forum legend (in his own mind) but it only says $@#$#@ legend(in his own mind)

I know that it blocks out certain words that are “naughty” are you sure you spelled forum right?

Testing… (I changed my user title.)

Hm… yeah, it does do it. Weird. My guess is that is done so that people can’t put “forum admin” in their user title and confuse people.

Correct. Some words like ‘admin’ ‘forum’ and other things were disallowed by vBulletin in the default install.
