I've been involved in a handful of issues on drupal.org. According to a search for issues where I participated, it's about 3,300 issues. That's a lot of typing. A lot of that typing was on duplicate issues where I probably wrote variations on the same words. Unfortunately when I'm feeling rushed through issues I can be a little less friendly to people than is ideal. Fortunately there's a little tool that can help make this less tedious and provide more thoughtful messages to the people who submit these bugs.
