Can I test myself to see if I'm on the Asperger's spectrum?

I had never heard of Asperger’s before the Sandy Hook Elementary shooting.

I’ve been hearing more and more details about it lately, and encountered some people that are highly functioning…sufferers?

I fit a lot of the profile in a very highly functioning way. I wonder if there is a self test, or an online test I can take to have a better idea?

Anyone here highly functioning Asperger’s?
