The traditional restrictions on web usernames are things like only
alphanumerics, and usually lowercase to reduce user confusion/burden
remembering.
I was wondering, why? They seem quite arbitrary in the modern day world.
Why not allow (embedded) whitespace, punctuation, and so on?
The only thing I can see so far being a problem is if the username was
later used for an email address. But, taking that possibility out, what
other reasons are there for these restrictions?
s/^\s+//, s/\s+$//, s/[^\w ]//g, $_ = lc $_ for $signup{username};
unless ($signup{username}) {
$messages = "Your username must contain some letters and/or numbers.";
$signuperror{username} = 1;
}
