The first experience for new users to the English Wikipedia

That's why I'd prefer a simple Template:Help Me rather than having assigned mentors. That allows a lot more editors to go through the list and help out on the things they know about, while skipping what they don't know about. (It also avoids a newbie being indoctrinated by someone who may not always be right but has Very Strong Opinions.)
