We're glad to hear that you'd like to contribute to Dispatch! Please review this document for information about how you can contribute to Dispatch.
Dispatch maintains a mailing list where you're free to ask any questions you have about how to use Dispatch. The mailing list is monitored by @farmdawgnation, Dispatch's current mainainer, and a handful of Dispatch users.
You're also free to open an issue on the project and we'll be happy to look into your issue.
If you're interested in making contributions to Dispatch, we'd be glad to have your help! For anything beyond obvious bug fixes, before you're off to the races, please make sure there's an open issue representing the work you'd like to do and that @farmdawgnation has agreed to have you do the work. This is largely to ensure that your work isn't a) something that someone else is already working on and b) is in line with the long term plans for Dispatch.
By making a contribution you agree to license that contribution to us, and everyone else under the terms of the LGPL Version 3.
A condition of contributing to Dispatch is that you own your contribution. If you do not own your contribution you should obtain written permission from the owner of the contribution and present that in an email to @farmdawgnation before signing the CLA.
