In reply to mikehike:
If you're happy with single pitch anchors then there's not much you need to learn
technically, the difference comes in just spending a few minutes thinking about organisation and stance management which is something that you can't really pick up from a video/instruction book.
A couple of points to bear in mind:
1) Firstly, when you get to the stance, make sure you know where the next pitch goes (this applies as much to swinging leads as well I guess) that way you can plan accordingly.
2) Think about where the second is going to stand (so you can belay them to that side), where the dead rope will go and where the best position will be for them to belay you on the next pitch.
3) When they arrive and clip in, make sure they clip in underneath your crabs and always keep your end of the rope on top of theirs.
4) Don't turn around! If you get to a big stance it's really easy to turn around without noticing and you end up with twists in the rope, try and treat the ropes as being parallel, red on left blue on right for e.g.
5) Lapping the ropes over something (feet, tie in point, sling, big carabiner) makes things a lot easier imo, although if there's a big stance there's no need.
6) I personally don't see the point in a "cow's tail" for this kind of thing, if you've got a single attachment point (i.e. belay built from slings) then it's a lot better for the second to clip in with a clove hitch on the rope - more shock absorbtion, easily adjustable and less clutter. Obviously if you're connecting to all the anchors with the rope then you wouldn't be using one anyway.

P.S. I'm probably not the best person to be giving advice as I still find new, inventive ways to create clusterf**ks on multipitch routes.
