After the FOSS4G conference in Firenze, I realize I met many people who are in Zürich and maybe some other parts of Switzerland but not part of the SOSM community.

What is the best way to point people to a welcome resource or give some kind of invite to join discussions?

Should we consider any additional channels?

Previously I proposed making a Facebook page (not group) which serves as a good way for me to use some advertising credit to promote the page to demographics in Switzerland as an advertisement. But ideally that's not the central place just a pointer toward mailing list and other places.

Is there any newsletter that may be more consolidated than the mailing list (could link to top mailing list topics).

I am still new but definitely interested to have a good link to send to people to get more involved if they are totally unfamiliar with mailing lists and need a point of entry.
