The group doesn't lend itself well to supporting the StackScript, and I needed to use VCS to keep track of changes to the script. I was going to use Github, but their issue tracker sucks. I won't actually be releasing any files, so I didn't want to create a full-blown project, so I setup a sandbox project to host the source code for the script and to track issues with it:
http://drupal.org/sandbox/justintime/1176768
I do have permissions to create new projects on d.o, so if enough people say they want http://drupal.org/project/mercury_stackscript, I'll promote it to a full project.
