Depending upon your skill level, you could do just about anything you want to. We have an open source, you can read, write, or whatever you'd like. If you think that's something you're interested in, just check out our
repository and see if you can find anything you'd want to do. You could also start your own server, write Perl/Lua for it, and maybe even create some web stuff like the PEQ Editor that we use or something similar. The possibilities are rather endless, all it takes is direction.
