Hi blondiecrt1 - this can take place anytime! What we have done in the past is give people several weeks notice. Because of the various locations and such I have found it better to pick one thing that everyone makes versus an entire meal from soup to nuts. It also needs to be something that most everyone can get/buy. If you have a great chicken, or pork, or steak, or beef, or blah blah, then start a new thread and "invite" everyone to dinner - It could also be a salad, or a vegetable, or a side dish of some kind. If you think your entree just wouldn't be the same without a certain side dish then post both recipes and see what kind of takers you get. It could be that over a period of days people will make the dish/meal instead of all on one night. Just don't be discouraged if not much happens. Even though we span the globe "life" has a way of interfereing with the best of intentions!
So, if you want to, start a new thread in this forum inviting everyone to dinner (pick a date) and then tell us your menu giving us recipes.
