GitHub added the ability for project maintainers to add issue and pull request templates to projects.

To add an Issue template to a repository create a file called ISSUE_TEMPLATE in the root directory. A file extension is optional, but Markdown files (.md) are supported. Markdown support makes it easy to add things like headings, links, @-mentions, and task lists to your templates.

Thinking this will prove quite useful on some of my projects.
