Some of the links in the above posting guideline are out-of-date / no longer in existence. Do you want a volunteer (me) to vet the list contents and perhaps recommend replacements/alternatives? They majority seem to link to some form of web archive for some reason even if the sites themselves are still there and working.
It would be very helpful if you compiled a list. In case you need them, here are the ones which were in the Posting Guidelines.
