I don't think one will find an adult with autism, coming to an online mental health site asking, "Do I have autism?" I don't think there are any posts here in this forum by anyone diagnosed with autism (and I'm not sure but don't think there are any/many from those with Aspergers).

Yes, I know several adults with Aspergers but, even those diagnosed as adults did not first come wondering if they had it to an online mental health site, they had other adults, usually parents/care givers/therapists who were helping/supporting/involved in their lives who were working on finding out and getting a diagnosis. I've been on several online mental health sites with these adult friends and worked in a residential school for mostly autistic children/other children with developmental disorders and my daughter-in-law is a social worker working full-time supporting adults with developmental disorders so they can live in their own apartments instead of in residential/assisted living facilities and quite a few of them have computers.

It is my experience that adults with developmental disorders may enjoy researching online for ways to cope with their disabilities; but I have yet to meet, in nearly 20 years online, anyone who was diagnoses with an autistic spectrum disorder as an adult, through mentioning it to their doctor after questioning peers in an online mental health community.
