Allow certain usergroups to use certain custom bbcodes

[Boko577]

Hey everyone, I'm looking for a mod that will allow me to make it so that I (the admin) can use certain custom bbcodes such as iframes while no one else can. I really want to be able to use iFrames, however, I cannot because then others could use it to potentially leading users to a site with a virus. Is there any mod that will do this? I'm also looking for a mod that will allow you to hide custom bbcodes from going onto the bbcode list where people can see it.
