We are using a mock github project, "do something", to track current tasks in the CoMakingSpace and coordinate their process.
You may find labels with "issue #..." or "Help the space!" on a couple of things in the Space - please look up the issue before attempting to use those tools or areas, it might be a critical problem!
Entering broken (or sometimes lost) things into the issue tracker is a key part of your collaboration with the other Makers and resolving issues is of course really nice as well. You can also post a little "Help" sign to conveniently alert others of the issue! We usually have a couple of those lying around in the common room, feel free to print more when they are out :-)
