As a new member of the site, it occurred to me that someone just starting out with trying to live sustainable would not have a readily accessible way of finding out where to start on our site. I'm sure there are plenty of good questions out there for people who are new to sustainable living (the practice, not the site), so I thought a meta repository collecting these questions in one place (maybe even ordering them with the most helpful to getting started at the top?) would be a good idea.
A Community Wiki answer is probably best so we can make lots of small adjustments.
