Classify adds to your tablist a live description of what others are currently doing: (m)ining, (f)ighting, (e)xploring, (b)uilding, and (i)dle. This makes it easier to find other players for projects or adventures.
Classify is a part of the Heapcraft project: a group of computer scientists and social scientists offering open-source collaboration tools to server admins, like social compasses and real-time visualizations. We believe Minecraft can tell us important things about creativity and humanity. Contribute to science while helping your server: http://heapcraft.net
Important Note: Classify sends behavioral data to a university-hosted server and performs periodic self-updates, by default, though you can turn these features off. We will use your data to serve your visualizations, to improve the other plugins automatically, and ultimately in our academic research on cooperation, education, and creativity in games. Your trust is vital to our success, and we work hard to earn it: http://heapcraft.net/?p=privacy
