Good to hear that there is some interest! I had backburner-ed the project for a couple months as I had some sites that needed to launch right away, but perhaps this weekend I could get that set up. Some of my clients would be very interested in it as well, so I guess now is as good of a time as any to get it going. Would any of you be interested in giving it a test run with a mailing list if I get it ready by, say, sometime next week? If so, please feel free to PM me so that I can get you some code.
