justCheckers is getting with the times and moving over to using Git as our main revision control system.
Git is a much more flexible system and I can manage contributions from the community. If I hesitated with giving out commit access, it was because there is far more trouble with dealing with merging code and dealing with radical changes in Subversion than in Git. So I am a lot more willing to reopening the project to a full team.
I will update the downloads page with instructions on how to access Git later this weekend. In the meantime, feel free to visit the justcheckers SourceForge project page for instructions on how to checkout the code in Git.
