You can customize the MOTD you see when you login (with the exception
of what server you're logged into and some other info) and this
includes colorization support via minecraft color codes (you need the
special color code character that minecraft uses though, the example
motd.txt has an included rainbow you can work from.)
Hopefully fixed an old bug with the logger writting to the disconnected
client session which causes a ton of exceptions because the session is gone.
