Sweet. I guess i made a thread to remind you all then
Well there is a mod for vBulletin that does this. In vBulletin you can code it so that you can disable certain codes in desired pages.
For example, if this is "register.php page" then do NOT display this code etc..
I think SMF is great but IMO MODs for it is still lacking.. I prefer how I can install products/plugins in vBulletin.
