I mentioned a while back that I was using Google Apps for Your Domain to handle my email, and I discovered a lovely side benefit. By pointing my MX record for tanglebones to Google, my main account is a catch-all for any emails sent to @tanglebones.com. So if you were to send something to admin or webmaster or sysad (or jackass) @tanglebones, I get the message in my email.
So when I fill out a comment card in a restaurant or sign up for a service, I can be sure that as long as they get the host right, I’ll get my email.
And when your email address is “jemaleddin” that’s a big help.
