I sent an invite link from one of the locations. The link email came and he began to register, however the captcha was one of those dumb "mark the buses" types that keeps repopulating endlessly. After about 5 times he refreshed the page to get a new captcha, by which the page announced registration was complete and a link would be sent to the email.
The email never arrived. Following other similar posts, we tried using a private browser session using the forgot password link, but that never arrives either.
How do we get further help here?
