Add a section that strongly recommends avoiding corporate and confidentiality notices in email footers.

Please add as requirement that all emails have the following signature.

[[[ To any NSA and FBI agents reading my email: please consider    ]]]
[[[ whether defending the US Constitution against all enemies,     ]]]
[[[ foreign or domestic, requires you to follow Snowden's example. ]]]

[Lastique]

Whether you are serious or not, I'm not going to add such a requirement. No footers, period.
