[igrav-steering] [igrav-announce] The problem on stationary states in self gravitational field

[Nicolas Arnaud]

Ciao,

Besides guidances that would indeed be useful, I would suggest *not* to 
have a mailing list in which people can subscribe freely *and* post 
freely. That's a noble idea but I don't think it works in the real 
world. And I would even go one step further, in the sense that any list 
whose members we don't "know" (in a broad sense) should be moderated.

Cheers,

Nicolas
