I've got an excellent programmer "at the ready" for a multi-threaded email account verifier. You'd simply select what email account type the verification emails are going to (AOL, Gmail, Hotmail or Yahoo) and plug in your username & password & press start. It would then minimize to the task bar and continuously check for any incoming mail. It would open the emails as they come in, scrape ANY verification links and visit the URLs to verify the accounts. It would be multi-threaded up to 25 connections, so if you choose to not have it running in the background but would rather "do it all at once" it would only take a couple of SECONDS to click & verify HUNDREDS of accounts. All of it would be done completely in the background. No open browser window. Just a very small UI where you hit start and that's it.
