Open Source Labs (OSL)
Chris Bruner suggested that we nominate Drupal for the FLOSS Fund, citing their donations page. This page announces that the host for Drupal.org (and a whack of other projects, including Busybox, bugs.debian.org, Gentoo and many many more) is the Open Source Lab. They have a Rackathon which allows people to help cover their costs.
These folks are developing a little software themselves, but the real reason to support them is because they are making it easier for so many other projects to develop great software.
We can make a donation via credit card. See the contributions page.
(Paul Nijjar nominated the OSL.)
