On a less serious note, each core member has his own web directory now
(or is able to claim one). provided that you already have an user
account on yolk, simply create a directory named www in your home
directory and store all public files in it. The public URL for your www
directory is /~USERNAME (although this might soon change to
/people/~USERNAME).
P.S. some site functions that are dependent on the domain name might
fail. RSS is an obvious example. everything else should remain functional.
