My friend’s web hosting provider went out of business, taking his site with them. They’re holding his data and they own his domain name, so nobody can transfer it. Once everything gets straightened out, I’ll be hosting his site. I found that Dreamhost lets me create a full-fledged separate username with its own home directory to host the site, so it doesn’t have to share the same home directory with everything else, as all of my sites currently do.
