inform user of password has requirements (6 char, one number) in prompt

[andrewufrank]

a very simple change in the prompt when asking the user to register a new account: tell ahead of time that the password must include a character (besides the mentioned being six char long).

it is frustrating and confusing to have your input rejected and be forced to start afresh for missing a condition which you were not told.

aside: i think asking for a number (or any combination of such things as capitals, etc. etc.) is pretty useless. useful are only longer (non dictionary) passwords - and those should only be asked to protect secrets of value.

In the code we have

            , label ! [thefor "password"]
                    << ("Password (at least 6 characters," ++
                        " including at least one non-letter):")

So it seems that the form does include this information.
