<emphasis>Do not leave the
<quote>Summary
</quote> line empty.
</emphasis> The PRs go both onto a mailing list that goes all over the world (where the
<quote>Summary
</quote> is used for the
<literal>Subject:
</literal> line), but also into a database. Anyone who comes along later and browses the database by synopsis, and finds a PR with a blank subject line, tends just to skip over it. Remember that PRs stay in this database until they are closed by someone; an anonymous one will usually just disappear in the noise.
