@NicolasChabanovsky hello! Thanks for coming back to this and sorry for the delay. I think the simplest would be to link the faq mentioned by @MartinSleziak in the help center. This one math.meta.stackexchange.com/questions/29265/…
Sorry, I thought that I am just talking with a regular user. (Later I have noticed the diamond, but still, I missed CM. Which is the reason why I explained some things which all involved people already knew.)
As a side note, some users asked a few questions today in Mods' Office, maybe for some of them moderators are in the best position to answer. (Although I have pinged Xander Henderson there, so at least one moderator is quite likely to notice that.)
I think that at least some users would certainly appreciate link to the search-FAQ on meta in the help center - the idea to do that gained some support (both in upvotes and in comments).
