Well i managed to download it off the web page (not obvious), so I think we are OK for now. but for information, we couldn't even do it by ssh:
$ git clone ssh://email@example.com/jmstester.git
Cloning into 'jmstester'...
angrybob1000: Does not have access to git repo jmstester.git
fatal: The remote end hung up unexpectedly
I tried to clone the git repositories with no success too. I can checkout the svn repositories, but anonymous git access does not work. Does anybody know the method how to clone the repos anonymously?
