It was on planetearthsingles.com where someone suggested that I might be affected by Asperger’s. She saw herself in the spectrum and had an official diagnosis. So, this could be a site, where understanding people could be found. However, it is not a dedicated aspie-site. So maybe just write in your description that you are looking for other Aspies or Aspie-friendly people. In general my impression is that people there are more understanding and friendly than on other single-sites.
