Being unfamiliar with vB's Control Panel (haven't installed vB yet, just researching), I'm not aware of how it works.
When you say "Just type in what you want to use and what it should be replaced with" do you mean replacing one tag with another? As in, [bold] = [dark]?
This would most probably not work for TWiki style text formatting... as shown here:

any further ideas?
thanks...
