You know, the IEEE site has plenty of room for minutes.
They're not updated right away because I can't always
get through to Dan's machine, and I guess he has silently
refused my many requests for him to mail me the minutes
directly.
Jason
I don't recall any such requests, silently refused
or otherwise. In any case, here it is. Enjoy. - Dan
