Let's see... Now you are testing my memory!
Originally the board started off as the recipe board, but soon scrapbooking became a rather hot topic on the CB and someone suggested combining it with Recipes since neither was a huge topic by itself. Sometime after that the newly named Recipe/Scrapbook board was born. There was some talk of opening it to all crafts, but there don't seem to be too many other crafts discussed on the boards.
For a while people were putting R: before recipe posts and S: before scrapbooking posts, but recently that seems to have fallen by the wayside.
Should we start doing that again?
