I have member-indexed 19 books. I currently index about 20-25 recipes in an hour, and I spend about one hour indexing per evening (after work). Of course, when I first started, I was much slower (maybe 15 recipes per hour). With practice, I learned the rules, recipe type categories etc better. It helps to have a fast internet connection. Also, I recommend beginning member-indexing with a shorter/simpler cookbook, perhaps focused on a specific ingredient or cuisine that you know well. I enjoy doing it, and it gives me greater knowledge of my cookbooks.
