This video was a good overview, though he didn't explain how to add new tasks (go to the bottom of the screen). I'm trying BlancList again now that it has improved some since I last tried it. I like very much how it helps you focus on just one task at a time, by putting it in big letters on your screen; in conjunction with my favorite pomodoro webapp (mytomatoes.com), I am enjoying doing things with this online tool.
However, we've spotted that someone has made a video on how we approached FV, might be useful to some people here: http://www.youtube.com/watch?v=rkrrPnSj4bw
