In the UK/Europe the main group to be on is Autism Biomedical Europe
http://health.groups.yahoo.com/group/Autism-Biomedical-Europe/
This lively group has over 750 members.
Its main focus is on biomedical interventions but parents also discuss schools, statements, Disability Living Allowance and other benefits and the latest news. However it always seems to come back to one central topic - gut problems!
Mandi is the group leader and one of the UK's most knowledgeable parents. To join this group just click on the link and include information about your situation.
