From the Linuxbox Web
“Linuxbox is proud to offer FREE hosting to the GNU/OSS
development community! As an ongoing effort to raise awareness of
Linux and other Open Source projects that we have been using to
create our business, we’re offering free stuff in return! All of
our services are available to you at no charge, and the only
restriction is you actually have to be developing something.”
