This doesn't look good. However, like others here, I struggle to think that Billy has passed away until we get some confirmation. On the other hand, I find it weird that he hasn't picked up on this thread, either from visiting the forums (even just to lurk) or the PM's and e-mails sent to him.
I would love to see him chime in here, saying "Hello" and calm us all. But I'm starting to think that it will never happen...
I will keep an eye on this thread in case something new pops up.
Here's to you Billy - Cheers!
