I want to force my new users to only use underscores instead of spaces in their username.

What is the regex to prevent spaces between words as well as leading or training spaces?

I thought about using javascript, but this is not the real answer I think.

I would like to see better error reporting capability from Links when a user incorrectly enters data into any of the links forms. Like "The username field must not contain any spaces". Or whatever based on the regex. I know this can easily be done with javascript, but doesnt this limit users or cause potential problems for some browsers?

Thanks guys.
