Warning: I've only been playing since 2001 and have never been to hell or the Silent Tower.

My impression of things is that the rules regarding secrecy are now much more tightly enforced when compared to the days of old. So your posit about ST not having a place in today's CF is really weird to me. I've always be a "glass is twice as large as it needs to be" guy so bear with me when I say my interpretation of what you're saying is that we now that we enforce secrecy we need to get rid of secrets. My suggestion would be to realize that puzzles are fun and complete secrecy is impossible. It won't be long until all of the wand locations are known and anything of that nature is just a ticking time-bomb of open-ness. Information wants to be free. There's little you could do about it. The problem is that many times when people on the immortal staff begin to come to grips with the reality of secrecy, they get their feelings hurt and huff and puff about quitting altogether. And every time the "punishments" punish the majority (non-cheaters?) more than they punish the cheaters. Because the cheaters will tend to gather the newer information than non-cheaters on average. My point is, change it from time to time to keep things fresh and interesting, but try not to get so upset when the inevitable occurs.
