Dear Erik and crew,
First, I'd like to congratulate you on the fine work you've been doing with both Dragon and (especially!) Dungeon. You actually succeeded in getting me to subscribe to Dungeon (I've never subscribed to a RPG mag before, even though I started playing/DMing almost 20 years ago now), if only for one reason... the rise in Greyhawk content! So far, so good! I sometimes buy Dragon, but haven't gotten around to subscribing... yet...
That having been said, I do have a request for an article (or two) that I would like to see appear in Dragon (I actually would prefer to see it come out in Dungeon, but I think that's unlikely to happen). The subject would be secret door mechanisms... how do they work? I often have a hard time describing this in a plausible way to my players. There are plenty of source books on traps, but nothing on secret doors (if there is and I missed it, even within an older issue of Dragon, then please point me in the right direction!). One article could focus on "mundane" (i.e., non-magical) secret door mechanisms, ideally based on real world historical examples. I really like the way recent articles, e.g. "Down the Drain" and "Get Lost!" in Dragon #326, include references to real world history... make sure your authors keep doing that! A second article could focus on magical secret door mechanisms.
Erik and crew, thanks in advance for reading this note, and keep up the great work!

p.s.: Anyone else interested in the subject of secret door mechanisms?
