I'd like to add my thanks too! I'm on EYB every day - either checking out the notes, searching for recipes to make, deciding whether to buy a new cookbook or doing a bit of indexing (but nowhere near as much as Astrid!).
In the last few years I've used the cookbooks that I have to much better effect - last year I made a resolution to make a new recipe every week and ended up making about 120 new recipes over the course of the year; this year I've managed over 130 and it would have been more had arm surgery not stopped me cooking for a few months. And I've become a much, much better cook in the process! EYB truly is a marvellous tool.
