I want it to match all alphanumeric characters (digits and letters, uppercase and lowercase), spaces " ", underscores "_", dashes "-", and dots "." and it should be at least 3 characters long and not more than 32 characters long.
Would it be..
^[A-Z0-9.-_]{3,32}+$
^[A-Z0-9.-_]{3,32}$
^[A-Za-z0-9.-_]{3,32}+$
^[A-Za-z0-9\.\-_]{3,32}+$
Which one would be correct if any (I need it for vbulletin forms) ?
Thank you in advance for the help.
