They *don't*, only *English* ones have left hand threads for Flammable
gasses, which indicates the contents. Camping gas which originates in

Propane bottles, and after all these years I have to work it out every time
I touch one :-(

newsreader, say Agent, and a newsserver, say news.individual.net. These
will allow them: to see only *new* posts, a killfile, and other goodies.
