OpenTDM is now available as a github project.
If it's of any help, I've imported r1q2 onto github, preserving commit history of all the public releases:https://github.com/tastyspleen/r1q2-archive
I ended up writing a script to download all of the releases at http://www.r1ch.net/stuff/r1q2/src/
and import them sequentially into the github repository, so the full history is preserved.
Thanks for putting OpenTDM on github!
