UnalloBot is an IRC bot that facilitates a number of functions for Unallocated Space. It started as a way to check to see if the space was open and grew from there.

Related: IRC & Minecraft

  • Version 2.5 Major addition to 2.5 is the ability to add new commands and edit old commands on the fly by editing botfunc.py then echoing "update" into the irc named pipe.
  • Version 2.7 Saw the inclusion of command approximation and the removal of several command aliases which can still be used via the aforementioned approximation (Levenshtein)
