Re: Game Folders suggestion
I think there have been similar requests in the past. I believe often it came down to concerns about GMs being able to keep up with all content in all folders.
However, you can currently [sort of] do this, if you place certain types of threads in certain groups, you can encourage your players to use the Filter feature which was implemented.
Filter on A for Character Creation information
Filter on B for Campaign Background information
Filter on C for Calendar and past story summaries
etc.
I know it isn't as simple as what you suggested, but I wanted to point out there is a 'sort' of a way to accomplish this if you have a significant need for it right now.
