Well, one thing that you could do would be to start a Yahoo group - it's free, and it's easily searchable so that others would be able to find you. It takes minimal work as well.
The way I see it, create it and see what happens. If it's nothing then you have lost only a few moments of your time - if you create a new community that allows people to come out of the woodwork, then the whole poly world is better for it!
