I think the Wiki/FAQ is a good idea. It would also be useful to hold things that aren't discussed often, but are good to know. Long term planning is also a good topic, which Doug has already state he was going to consider.

ETS has historically been "wilderness" survival, not urban. "Wilderness" provides a setting in which YOU are pretty much in control, the urban situation puts you into an environment where legal issues are a concern along with the fact that most people aren't afraid of other people, as much as an alligator would be afraid of a person.

Things might start to drift into what is considered taboo subjects like self-defense, weapons, lock picking, hot-wiring vehicles, abandoning the elderly/disabled, fortifying your residence, and others.

I'm not trying to be TEOTWAWKI, but there are some real life questions that may have be thought about in an urban environment, since things could, locally, deteriorate really fast. The TEOTWAWKI line is getting a little more blurry. These "hot" topics could cause problems.
