I think putting in how to make presets, and downloading items/markings/maps would be a helpful section of an FAQ. It seems like a lot of newer players find some of the tutorials out there a little hard to understand, and it'd be nice for them to find the answer in one place.
Maybe throw in something about the login page, as well? Quite a few new fluffs don't realize they have to keep it open, and if they checked an FAQ to have the answer right there, it could help more of them get online.
How to put images into forum posts/siganatures/profile pics if forum stuffz could make it into the FAQ as well! Possibly along with some of the usable forum codes, since newer forum-goers seem to ask that sometimes, too.
I think making a Feralheart FAQ would be beneficial to everyone in the end. I'd love to see one implemented!
