Hi Matt,
That is great news to hear! Thanks to everybody who helped
out while I had to attend to my new family.
We got back from the hospital today, and everybody is fine,
so internet access is easier and I'm able to see/respond
to emails now.
Please let me know if there's anything you need from my
side. I am thinking that I can stop in at least briefly
at IU next Monday, so I hope to catch up on things then.
