QuIRC is an inclusive project. The fact that it even exists today is thanks to a diverse cast of contributors from around the world. Indeed, we would not be here if not for the hard work and dedication of many people who, elsewhere, might have been discriminated against simply because of who they are.
For that reason —and because it's just The Right Thing To Do™— everyone in the QuIRC community is expected to be professional and respectful at all times, whether collaborating on code or just bantering in our IRC channel. Basically, don't be a jerk, don't make personal attacks, and listen if someone else tells you to back off. Listen harder if more than one person does so.
Everyone involved with the QuIRC project is a person, not a collection of labels (unlike our issue tracker, which is the reverse). Remember that, but don't forget to be awesome!
