Automatically create hyperlink from keyword

[dontpanic]

I am wondering if there is a way to have posts containing certain preconfigured keywords (such as support, MCSE, etc.) appear not as just a plain word, but instead appear as a hyperlink to the preconfigured location.

For example, if someone in the forums posted the word support (just as an example), it might link them to a forums support page. Or if the word contact was posted, it might link them to the forums contact page.
