Font tag?
 

Hey I noticed that the BBCode Color tag ([ COLOR = "MyColor" ]blah[ / COLOR ] - without spaces) in the forum changes into this:
I don't know if it is possible or not to change this in VB but if it is then you should change it to meet standards.

That's default vB output. I think it's possible to replace it in the acp but I'm not sure.

You cannot replace this built in bbcode, if you need to change it then either making a plugin to hack this or manually change it in /includes/class_bbcode.php should do :)

That doesn't sound too hard to do. But then again I'm not the one that has to do it.
