as for the regex. Quite why you would want back ticks, bars and square brackets in usernames is beyond me. is your site called www.easy.to.hack.com?

the hyphen should go unescaped at the end, I have no idea if backticks need escaping, or if they or anythig else is being weeded out by vb.

/^[ a-z0-9`\^_\[\]\|-]+$/i

or

/^[ a-z0-9\`\^_\[\]\|-]+$/i

are my guesses
