Sorry for taking the conversation away from Gravity Forms.

One thing I would like to know from anyone who is actually using GF on a live site: how intrusive is whatever form of copy protection they are using? I seem to remember interviews in which they described some sort of call-home validation integrated into the upgrade process. Does this mean that you have to enter your license numbers each time you upgrade? Could temporary validation problems, such as the ones that afflict the Windows validation process, prevent a form from working? Could they even prevent the entire site from rendering?

I haven't head of any problems, so, that in itself suggests that the copy protection is unproblematic but I would like to hear it first-hand from anyone who is actually using GF, as opposed to people who are just members of the affiliate scheme.
