Some forums seem to discourage members from replying to "old" threads -- as though doing so is some kind of violation of etiquette. (On other forums, I've seen people get made fun of for resurrecting "dead" conversations.)

I've never quite understood that. The point of a forum is to encourage community & communication - there is no "best before" date on those goals.

So, if you have something to add to an "old" discussion, or a question to ask, please feel free to post.
