Currently you have to edit the logbot.py file to change settings. As a result, you can't easily run multiple instances of the same script.
It would be nice if the script only used the current constants as defaults, and allowed for a config file to be passed as a commandline argument that would override the defaults.
I wouldn't mind implementing this myself, but as I'm new to Python and don't really know what the config file standard is (YAML, JSON, ini, etc?), maybe we could discuss it in this ticket. :)
