Need test users

I am working on a research project to evaluate the potential of using wikis in math education. I am looking for some math teachers (at any grade level, or college) who would be willing to become test users. This would entail using the wiki that I set up for at least one week - navigating the pages, and trying to generate content on various topics. After that, they will be asked to take a brief survey.

If you, or anybody you know, are interested in participating, please email me with the words "Math Wiki Research" in the subject line. (Don't reply in the comments). If we don't know each other, please have the email come from some official-sounding domain.
