If you're upgraded, drop me an email at support@youmescript.com, and I'll send you a link in a few days or so. Should be totally usable, though some things will be a bit clunky, and not all features will be in.
The point is to get genuine feedback on how to make it better, and which feature or features need to get done first. Looking to release in the next few weeks.
Ta!
