I feel like I've been waiting forever and I know that there is alot of demand for this but I feel like I've been waiting forever to receive an invite via email/Ancestry message to do this AncestryDNA test. I heard that FamilyTreeDNA is also excellent but other websites are waaay too expensive and Ancestry.com has it for only 99$ so I would really like to try it with them. Is there something special that I have to do to get on their waiting list or something? I've went to the Http://dna.ancestry.com multiple times and it told me to keep an eye on my inbox. Perhaps I'm just too impatient, haha.

Also with the test if it shows that I have American Indian ancestry will it at least show what tribe I am probably descendent from? and if it can't, does it at least show which region in the Americas. With a location it is much easier to determine what tribe.
