Right, only if the user chooses to change it in their user CP, I should have mentioned that. Otherwise, without modification they have to do it themselves if members of a secondary group. after importing my users to vb (from ubb threads) I had to take all of the mods and paid members one at a time and put them into a new primary group in order to force them to use the markup, that was fun

Here's the thread about it
