Had a hard time getting this going myself and went to their site and it was down so I couldn't read the docs or check out the forums! They were switching servers, oh no! I had a deadline so I emailed them in desperation. They were incredibly helpful and even installed it and got it running for me. I've never experienced great tech support like this before... I was really amazed. I configured the memberships (read the instructions carefully and you'll have no problem) and it works like a charm. I made my deadline and I couldn't have done it with regular ho-hum tech support... this whole this was resolved in a matter of hours. If you need thins kind of program, buy with confidence, it's worth every dime and more.
