Want to meet other autistic people

Unfortunately some of the local group information isn't updated regularly.  You could email the Community Manager with details of who you emailed and which ones failed - this would be helpful, I believe. 

People set up groups and sometimes they fold due to lack of support or because the organiser cannot sustain the commitment.  

I'm from Surrey and open to meet. 34 m

I tried emailing the Surrey NAS groups but all my emails bounced back. It was wierd

The Autism Services Directory may have some groups in Surrey of interest

Failing that, sometimes it is good to keep an eye on local media such as newspapers or Facebook groups to see if anything in the voluntary or charity sector is running in your area.
