I realize that this post is very late, but I have to ask... where did we find this idea?
I'm only asking because I WAS the admin on another forum, where we did this.
But I have another idea.
Why not a traveling cookbook?
People could try diff recipes, sign the inside cover, and we could go down the line with other members who would like to participate. Enclose a photo of something you cooked, and send it along. With all of the members we have here, this could easily be an activity that will continue for awhile! And we could have a special topic for recipe reviews. Have you done this before?
