I love potlucks- I don't think there's any better way to meet people and really connect than over food in a private home or apartment. I joined many potluck groups, but noticed almost all of them were for vegans or vegetarians. I wanted to make a more generalized potluck and dinner party group that includes non-vegetarians too. I myself am a former vegetarian (6 years) but still enjoy cooking vegetable and whole grain loaded foods, in addition to meat, poultry and seafood.
I also have a huge space perfect for entertaining. Problem is, it's 30 minutes out in Brooklyn. I definitely want to get some dinner party mileage in at my place, but I would imagine at some point other members of the group would offer to host at their places, which may be more convenient for all.
