To admins of PO/@Dilaton/@DIMension10: Concerning import of Phys.SE posts to PO: Unless there is a direct request from OP or one of the answerers for an immediate import, I would suggest PO to wait until the post has matured (a month?) on Phys.SE before importing.

One example: Only v1 of this was imported to PO, while the current version on Phys.SE is v6. It is very confusing to have different non-final versions of questions and answers crossposted all over the internet, and it is wasting potential answerers time. We can't rely on users systematically updating/maintaining all the appearances of their posts. Hence, it would be best to limit the import of brand-new still-active posts.

@Qmechanic ok, this is probably a good idea, thanks.
