Have certain "keywords" auto-linked ?

[z0diac]

I've seen other forums where in a post, certain words when you mouse-over them, automatically have a little floating window come up where your mouse is, with a link going off that word.

Eg; a message about cars has the world "Chevy" somewhere in the message body, and when someone goes over that word, a link it shown to a GM Chevy site (just an example)

Is a mod like this available for vB ??

I have a lot of messages posted that I'd like certain words be linked to parts of my main www site when those words are in someone's post.
