Hi, simple question really, i need a regular expression pattern that will remove all symbols such as... +-=)(*&^%$£"!

But I also need to retain the underscore as it's for a username... Any help would be greatly appreciated. :)

try this: [\+-=\)\(\*&^%$£"!]

This will match any of those characters. Note the escaping of certain chars. Depending on what you are using the REGEX in (javascript/asp/?) you might need to escape additional chars.
