Historically, they have the posts going back for years. There is always the danger that some sort of server failure is possible, but I think we are pretty safe. The threads are still there for the first game I joined almost a year ago. I've been doing my big posts in word because my spelling sucks, so I've got those archived. It wouldn't hurt to have your character backed up just in case some disaster befalls the server. Hopefully, we would have enough to continue with that.
