Note: I am not asking for help here, My own personal problem has been solved. This is a suggestion that might help other people in future with the same problem.
I was having a problem creating a proper, registered account. Someone on the Science Fiction community, where I was participating as an unregistered user, suggested I come to Meta to ask for advice. So I came here, and found that I need to register and log in before I could ask a question.
There was a big paradox there: I was unable to register an account, but I couldn't ask for help as to why or how without having an account.
In the end I solved the problem by asking for help on Science Fiction, and having a moderator migrate my post to here. Not an ideal solution. If I hadn't already been known on that community, it might have been closed and deleted.
I am probably not the only person ever to be stymied by this. There should be a way for users to find out why they aren't able to register without having to go through what I did. One way to solve this may be to allow questions from unregistered users here.
