When they try they get the message
"Sorry, registration has been disabled by the administrator."
That's what I got when trying out the registration stuff. (The captcha looks better, but still rather crap.)
But the thing is, I don't see where it is disabled. I made sure it's enabled under User registration settings, but that seems to be ignored.
Anyone an idea?
I'll keep digging around to see if I can find the culprit.
