We did this a while ago, but it’s time to do it again (the second Welcome post has almost 700 comments now). Hang on a bit.
EDIT: OK, I’ve done it (and anticipated the new year by a few days); I also changed the second post to send people to the new one. I also asked MBlume to do something similar with the original thread (because people keep winding up there).
I’ve takent he liberty of editing the relevant wiki page as well, to mention the current 2012 page.
