I tried, and tried, and tried to join that forum to no avail. All I got was a the same errormessage, labeling me as a spammer. I did a little googling and reached out to one of the webmasters there who told me to use the ‘Contact Us’ link to reach out. There was no such link, which I documented with a screenshot which I sent to him. He added the button to the page and told me that if I inquired through that link, someone would take care of the matter. I sent a message through the link and never got a reply. I tried joining again to see if that process was fixed, same result, same error message. When I looked a few days later, the contact us link was gone again. So I don’t know WTF goes on at that forum, I have never had that kind of problem joining a forum before or since, but I did learn that apparently if you have a problem over there, don’t expect much help. (If this reply violates any kind of ‘dirty laundry’ policy, feel free to strike out the offending portion.) I finally gave up and came here where I found not only a registration process that works, but a helpful and welcoming environment. PS, I tried to follow your link to the thread, but got only a password challenge screen, which put me right back where I started.
