Mike, this is great feedback for us! It's easier said than done since Beeminder is constantly changing, of course. :) See http://beeminder.com/meta/uvi

We'd especially love to hear about specific things that took trial and error to figure out. Ultimately we hope to have everything be so intuitive and self-explanatory that there's little need for a user guide. We're gradually getting there. You should've seen us a year ago...
