Force Guests to Enter Username via Javascript

[محروم.كوم]

Hi,

I installed this Hack to force guests to enter a valid username:
http://www.vbulletin.org/forum/showthread.php?t=148686

However, this error checking takes place on the next page and when you click back the post is lost -- more often than not.



I looked into the Javascript code for validating the subject and post length, but that seems very hard to extend with a custom check to force Guests from using a username that's not "Unregistered."

Do you have any ideas how to do this?

Thanks,
