Create an FAQs forum category on this site
Enable only certain users (community moderators, developers, etc) to add topics to the category on request from other users. This way, we wouldn't have a ton of redundant topics about simple issues (like category permissions and stuff).
And also, place a direct link in the site main menu.
IMO we should just add an FAQ section to the docs. Then we can translate them as well in future
Good thing we do have one! XD
Okay, in that case, I'll just mention one of you (or make a pull request for the docs) about each question that should be added to the docs.
But you should make the FAQ page's existence more known.
