I've archived all the main boards, and have created a basic template for the boards that will exist from now on.
Descriptions have yet to be added, which I'm about to do now.
The old boards also aren't closed yet. Just don't post in them for now.
Afterwards I'll backup as best I can. I still don't know what kind of backup system Prop has setup here. I do know that there's no way for me to save a backup locally on my computer, it can only be done on the server.
In any case, feel free to post in the meantime, though everything will probably be ready before anyone even reads this.
