First off, thanks to dagon who posted the link in this post.
While I've allready read a bunch of "before posting, read this", "Smart Questions" gave me a bunch of good new insights. I believe that document to be clear, precise and cover pretty much everything.
So, apart from thanking dagon, I'd like to suggest it as a sticky candidate in the newbie section.
While this post is obviously a good read as well especially since it includes some advice specific to this forum, I find that its format makes it harder to read.
But the main advantage of "Smart Questions" is that it very clearly explains not just how to behave, but also explicitly states why.
Perhaps it would even be possible to have the best of two worlds combined: some concise forum specific information along with a link to "Smart Questions"?
