@FrançoisG.Dorais : this question is for everybody here. What do you mean by "mission" ?

Objective or goal?

@FrançoisG.Dorais, @skullpatrol, the purpose of putting this link here is to inform users of the existence of this post on meta, so that they may come participating in the development of sites (complementary of MO) for massive collaborations (i.e., Polymath-type sites of quality commensurate with MO).

But @Sébastien, why don't you use the usual way of creating such a site rather than pushing the limits of MO?

@FrançoisG.Dorais : what do you mean by "usual way". I would prefer that the creation of this site itself would be massively collaborative. MO is THE model of math-site, but the most important is to attract experts, and we can discuss with interested people directly on MO's chats or meta. If people collaborate in the making of the site, they will be better engaged on it from the beginning.

@Sébastien: Maybe you should think about that some more. The French Revolution was an incredible event but it wasn't an usual event in any sense of the word.

@FrançoisG.Dorais : could you please be more specific, I'm not sure to understand your point ?

Basically, the history of France should be written in French :-)

That is the "usual way."

@skullpatrol : I'm sorry, but it's no more clear for me. Perhaps I'm tired...

@SébastienPalcoux The usual way of creating a site is to make a proposal at area 51.
