When in doubt I would look to more recent statements made by theymos. I honestly have completely disregarded it when I see the "local rule" though they are usually pointed to someone else. I say post away, let the Mods decide. This is a public forum and I don't see theymos encouraging these "rules", when there is an option available.

To bad for them if they forgot to make it self-modded, they can take their ball and go home.
