Feature Requests: Triathlete's Forum?

First off, I love this site!  It has been so useful for me and I love many of the features.  Please keep up the good work.

I've noticed in the Discussion categories there is a Runner's Forum, a Cycling Forum, a Walker's Forum, but there isn't a Triathlete's Forum.  Would it be possible to add that to the list of categories?  If there is a way I can do that I haven't found it yet.  Thanks for the assistance.
