I have mentioned issues with the documentation too. People are doing posts with tips, but you need some way to pull those together so people can actually find the information they need.
The Hive code is available. I was trying to see where the FAQ text is stored. Anyone should be able to suggest improvements. I'll ask around.
TBH Hive needs a Wiki. If they created it on the blockchain then you would need to use your posting key to edit it.
