Im trying to build a user login system, and when there is a new user, I need
to validate that they are usign using word characters ([0-9A-Za-z_] or
\w)... I have TRIED MANY different regular expressions to test this, but
none work. This seems so simple but I am missing something. I need a
expression that returs true ONLY if ALL the characters match \w .... Any
help would be appreciated.
