The Wiki software has a Donations link and no easy way of disabling it. Sorry.
We don't need donations. But there ARE ways you can help.
- Donate money to any open source project.
- Donate to the Free Software Foundation (FSF) who funds and protects tons of open source utilities which you and I use every day, including the GNU base for all Linux systems!
- Donate to the Internet Software Consortium (ISC) which maintains BIND, DHCP, and other immensely useful software that holds the Internet together.
- Sign up with HostGIS for consulting on your next project, or for a server. They're really good servers, really premium hosting worth the price.
