The next link does not appear when I select Other for answers in your enrollment process. I had to select KiCAD which I don't use yet in order to get the next link.

You should add an email verification step to your enrollment process. I have another email account that has a lot of people use by mistake, and it is a real PITA to get rid of those accounts.

For gmail accounts, the dots in the account names are ignored. mark.olson@gmail.com and markolson@gmail.com are the same email addresses, but can typically be used to create 2 different accounts. That shouldn't be allowed.

Thanks for listening.
