I came here to also complain about the CAPTCHA. I almost gave up after the 4th try but I really wanted to see what this was all about. I don't know what they are thinking with that monstrosity.

it is likely the email id you are trying to use is already taken up. If you scroll up a bit, there may a error mark near the email field (I had this issue and but was trying to change the captcha).

The first couple of times I tried the error message wasn't even being shown, but when I changed the username it worked.

That did happen initially but then it only complained about the captcha
