"Does Project Honey Pot support Open Source development?

Yes! We want as many developers as possible to help with this project. We use Open Source software and, where possible, have licensed the software that we've developed under the GPL. If you want to contribute to Project Honey Pot, drop us a line and we'll get you involved."
