Initial Description
I used to have the strlen block and the 2 preg if blocks each separately return false throughout, but lately I'm in a single point of exit mindset. I cannot take credit for the regexps - I borrowed them from someone who borrowed them. If the real author is known, please comment and attribute. I _did_ however make one edit, which was to increase the TLD portion from 3 chars max to 4 - to account for .info email addresses. One character - my big contribution! Enjoy
