There are far too many posts being made which have the same questions (Will be there be W? How do I Y? Is Z allowed? etc.) a FAQ page can greatly eliminate the amount of useless posts and we can have clear and transparent rules that people can follow.
Consistent patch notes will overall get rid of questions that are spammed every time a staff joins after game updates, a simple tweet or @everyone for every server shutdown can inform and reduce confusion by a LOT. I understand that there are already patch note announcements but they are rarely posted if they are even written on at all anymore.
