Do you think Pump19 needs a new Chem (the magic words that power a golem)? That can be arranged easily enough. Pump19 is built upon FOSS components and is itself released under the MIT License.
All of Pump19's source code is hosted on GitHub . There you can suggest new features, report issues, or even fork and contribute your own functionality.
There exist two distinct source code repositories: one for the chat golem itself and one for this website.
