Lounge is a chat system that is built on top of IRC.  As an option, people can also add and use non-lounge name by using regular IRC names.  Those names can be added to the bot so that they too also get notifications.

Just a reminder that the bot on lounge will send notifications to your IRC names... which means that your IRC names need to be registered and identified and set to kick people off who don't identify.  If you do not maintain the security of your IRC names, then the bot could be notifying people who use your unregistered/unidentified IRC names.

If none of this makes sense, then don't worry, you would know if you added extra IRC names to the bot for notifications :P
