I just convinced two teammates in a class that I'm taking to start using Mercurial. When I learned it a few years back I just read the main site, asked questions on IRC, and played with it to figure it out. However, given the pace of the class I don't think either of them are going to want to take the time to learn it that way. I was thinking of recommending they look over HgInit since they both have some Subversion background and that seems to be the intended audience. However, does anyone have a better recommendation?
Has someone picked it up recently and found a specific source to be particularly useful?
