I am contemplating making specific groups for specific spectrums parents, like Asperger Parents, Rett Parents.
I guess some topics would be very different depending of the type of autism (and severity) so it might be useful to have multiple goups, I am just waiting for more people to join to see how it can shape out.
I would definitively lead a PDD-NOS group, cuz that is what I know (or I should say what I am trying to know), but I am not sure i'd be the best for Asperger, etc.
