I'm consolidating things i've asked players on plurk before over here. These might be reference for what very new people might ask:

-It was unclear (except in AC posts which tend to get buried) which skill gains do or don't require "proofs".
-Skills a character entered the game with need to be clarified as... idk, "teachable skills"? "past jaunt skills"? something in that vein. I had to ask if they were teachable lol.
-I've seen players call Liminal, Psychic, and Combo Skills "Tree Skills". I don't know if this is official, but yes, there should be a collective name for these standard skills, because typing them all out gets old fast.
-Some sort of How to Do Dungeons explanation, even if it's just links to some good examples.
-Possibly a link to the game's Discord chat?
