At one time it felt like I was destined to be a PCB designer, churning out design after design for someone else's work. Now this is a very worthwhile and skilled job, but it wasn't for me, and so it is only occasionally that I get to design PCBs now. Unfortunately that means that I tend to forget work-flows, and fiddly little quirks and details. Come to think of it, I tend to forget some pretty big details too! When you have let muscle memory get on with things, it can be daunting when you come back to your CAD software.
I have a fair few notes which I have written up over the years, and I was even considering recording a video. This started me wondering what YouTube might have to offer. Altium have done a load of videos (hosted on their own site), but I have to say they aren't very helpful. At best they are rather "corporate". Anyway, to cut a long story short, I found these YouTube videos. They are clearly recorded by someone who knows what he is doing, and aimed at the more introductory end, but are very much worth watching if you need a quick refresher.
All these videos relate to Altium Designer, and are best viewed full screen. Videos recorded by http://www.youtube.com/user/elektroniskorg
