We use GitHub issues to track bugs and feature requests. To submit a new issue, navigate to the appropriate nasa-gcn repository and click on Issues.

Click New Issue and fill out the form. Please include a concise and descriptive title and as much relevant information in the comment as possible. If relevant, include steps to reproduce, screenshots, error messages, and anything else that may be helpful for us or others to pinpoint the cause of an issue.
