Jeff,
I wanted to ask you in particular, since you are one of the main moderators of this forum and also have provided extensive and very valuable discussions here: Do you know of or keep a personal backup (or multiple redundant backups) of all the excellent discussions archived here, especially in this Jeff Novick, RD forum? I personally feel that it would be something of a disaster if the server that hosts this forum ever failed and backups were lost.
I would suspect that the site administrators already keep this in mind, but I hope you also have your own personal archives of your work and discussions. Certainly if things were lost, it's all in your head and could be rebuilt, but that's no fun, when you already have so much painstakingly well-documented.
