You're welcome - would think the list of speakers will show up somewhere after it is prepared (perhaps they have not lined up all their speakers in the 2-1/2 weeks since their deadline - OR - they know who they are but don't want advance publicity to cause problems. These conferences have been cancelled elsewhere so they are probably walking on thin ice getting this organized and insuring it will actually occur.
Not terror related (I don't think), but the headline in the Rapid City (SD) Journal this morning reads:
"PLAGUE FOUND IN PRAIRIE DOG"
Article states that sylvatic plague is the same organism as bubonic plague.

IMO I believe they are just get more clever so as not to attract people like us etc.
