fail-safe is more important than SEO
I agree with you there. It may be plugin territory too.
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
