Re: Verify Email

Hey Chris: > Hi, this is my first posting to this list.

Good catch! Took a look at the ICANN site, the new TLD's are listed below. Looks like the longest one is six characters long, so I'd place an upper limit of 6 on that bound. So, here's my new expression: "^[a-z0-9_.=-]+@([a-z0-9-]+\.)+([a-z]{2,6})$" ANTICPATED TLD's: .aero – Societe Internationale de Telecommunications Aeronautiques SC, (SITA) .biz – JVTeam, LLC .coop – National Cooperative Business Association, (NCBA) .info – Afilias, LLC .museum – Museum Domain Management Association, (MDMA) .name – Global Name Registry, LTD .pro – RegistryPro, LTD <rant> Wow, how progressive! A whole seven new TLD's. WOW! :/ There were 47 applications submitted for well over a hundred TLD's. ICANN charged $50,000 just to _apply_. What a bunch of scam artists! Worse yet, none of Name.Space's TLD's were accepted. </rant> --Dan -- PHP scripts that make your job easier http://www.analysisandsolutions.com/code/ SQL Solution | Layout Solution | Form Solution T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y 4015 7 Ave, Brooklyn NY 11232 v: 718-854-0335 f: 718-854-0409
