Bhavin Gandhi has a very nice and useful post on how to report and deal with Emacs bugs. He explains the process and mentions many things I didn’t know. For example, you can help with the bug processing simply by verifying that the bug exists on your system too.
There are two servers involved with reporting and dealing with bugs and Gandhi explains what they do and how to work with them. It’s all handled with email commands and is easy to use. Take a look at Gandhi’s post to see how you can help with the bug process.
