Yes! You should e-mail us to set this up (one day soon it will be automated and you can do it yourself). Meanwhile, you should stake your claim in the DNS namespace by going to your favorite registrar (we can't recommend a particular one, but we can tell you what people have used in the past), spending <$10 for your name (for at least a year, maybe more). You'll have to tell your registrar to set your name to be an alias (CNAME) for artemis.hcs.harvard.edu. Then we'll set it up so that your site magically appears at your domain name. Amazing!
