It would be nice if you had a separate boards for...
1) Vegan/Vegetarian diets
2) Allergic/Intolerant diets
Why? Its much easier for us to find each other and get or give good answers. Personally, I would even accept one heading for both if you can come up with an appropriate heading.
? Alternate diets
? Special diets
I'm not sure if any of those titles would be considered offensive or not. lol
