Manual validation

Many of the guidelines, checklists, and validation tools mention
that you should not only validate by using an automated tool,
but also using manual validation by people with disabilities.
I thoroughly searched the WAI website but could not find anything
on how and / or where to do that. I sometimes see request of
webpage authors on this list if someone can have at look at their
site, but I wonder if this list is the place for such requests. Just 
imagine that accessibility becomes a well known issue amongst web authors, 
then a couple of hundred maybe thousands of such requests would be posted here.
