Hi:
Thanks for pinging him. I don’t know how to do that myself.
Also, from reading threads on here I know that you are into the cometary impact hypothesis dated 12,900 years ago. In fact Nova did a program on that called “Megabeasts’ Sudden Death”. It aired March 31, 2009. I don’t know if you saw it. I’m sure they will re-air it like this show, which was originally aired on October 7, 2008.
If the show was on Cable, I would not have been able to see it. With regard to how to ping someone, all you have to do is hit the Post Reply bloc on the comment space and enter their recipient name into the TO space. Another way is to go to Private Reply and send them a message from there. I hope this helps.
