Carl,
Feel free to try again. We enabled a different caching system last night that was causing a problem with our registration form. Didn't realize it till you pointed it out.
Everything should be working on there now, but if not, please let us know again. As always, if you do decide to take the plunge, but still can't get it to work or aren't satisfied, we have a 30-day money back guarantee.
Thanks for pointing out the problem,
Alex
