Their Dallas, TX 214 area code was changed many months ago. They used to have a web site, but I'm not sure if it's still up. I was originally told that there would not be a VFP version. Later there was a VFP upgrade, but it seemed like a half-hearted attempt so I switched to CommTools because of time-constraints.
