Two things that would be nice to see are two new forums:
The first (which was already mentioned) if a food forum. It would be great to have a recipe exchange or just talk about what people have been eating while in Europe. It seems there are a few people (like myself) that like to cook and eat. I would love to see a food or recipe forum.
The second is a stories forum. I know this could go under (maybe) the eurotrip pub. I think it would be cool if people would be open enough to share their stories. Funny stories, train stories, scary stories. Just fun things that happened.
