Remember to keep comments brief and to the point, but still descriptive and relevant. Try to avoid repeating things you have reported in the past, and allow other people's feedback to be heard as well. What we are mainly looking for is major new issues that we may not be aware of, such as recent (within the last few snapshots) regressions.
