Creating a bbcode for nofollow links?

Could someone help me?

I want to add an optional nofollow BBcode function to my Vbulletin 4 forum. The Admin panel allows me to make every outgoing link posted in the forum a nofollow link. But I don't want to use that option if i can avoid it because it disables member signatures as well.

Digital Point has one, with a corresponding closing tag b...place that does that would be awesome. Thanks

 

if you want the php code of that
you can look here

 

Awesome thank you

 

There is a setting in your admincp to do this

 

Yes but when you enable the nofollow setting in the usercp it disables every link, including member signatures.
