Cumaean???

This is the message as the crawl holds it, before anything here touched it. What the conversation shows has been through ingest: transfer encodings decoded, attachments dropped, quote markers repaired, and the archiver’s ? resolved into quotation marks and dashes. Those repairs are judgements and some of them are wrong, which is what this page is for. Email addresses are obscured here as they are everywhere else on the site, so it is before our repairs rather than byte for byte.

Not necessarily. Being fluid, the atmosphere is subject to positive 
feedback in that the tidal forces cause it to rise in a bulge, getting 
closer to the primary and thus being subject to stronger tides that make 
it bulge still more, etc.

The point is moot WRT to the moon; its "atmosphere" is a remnant, 
transitory puff of gas that was replaced twice over by exhaust from the 
Apollo landings.
