I thought a few people on here may be interested in this:
It's a UK peanut-allergy forum which aims to bring together all peanut-related resources for allergy sufferers - from supermarket shopping to where it's safe (or not!) to eat. The lady from itsnutfree.com also posts there to get ideas for what people want to have produced, so it's worthwhile dropping in to have your views heard!
It's run by a UK medical student - I don't know her personally but she posts on our Doctors' website. I hope it's a bit useful to you folk.
