From St. Louis Hackerspace Wiki
New hackerspace os project
AR OS will be a web-centric "operating system" to help manage Arch Reactor space.
Currently it is just a basic membership site, which is a heavily modified fork of NiceMember. I suspect that in a couple iterations most of NiceMember will have been either rewritten or massively improved.
Goals include managing equipment loans and donations of any sort, as well as integrations with various other tools.
