MIT-Church alpha test
From Church Wiki
MIT-Church is in a very preliminary alpha testing stage. It is unstable, it is hard to use correctly, and it is slow. This implementation is also expected to change (with little or no notice) in ways that will not maintain backward compatibility.
If you would still like to alpha test MIT-Church, you can checkout the SVN repository using username 'anonymous' and password 'anonymous'. (See the installation instructions for SVN address.)
