Thanks very much, Thomas, for explaining this. I had only read the
Digest of the list and hadn't seen your message yet, when I wrote my
last message.

Your presentation is amazing! Really wish I could have been there to
hear it and ask questions in person, but finances didn't allow it right now.

Michael Maddi's posting said that there are 26 new SNPs in the J
haplogroup! Are these all ones that Hammer has discovered, or just all
the various ones that have been added since the last YCC tree, including
Hammer's new ones?

Would someone please send me a transcription of the J section of the
poster ASAP?

Fantastic concept, congratulations! I can hardly wait to get going
with this. Very exciting prospect.

I'd like to discuss some issues concerning this with you, off list, when
we get a chance. But I must get some sleep at the moment, it's getting
late here in the East and I must rise early.
