lol - i find it comforting that HNSS shareholders won't be able to just walk in....
it also appears (if i am reading this right) that HNSS can show up and register at the conference - Sept 30th is not necessarily the deadline....it is simply the deadline for "pre-registration"...
9. What if I do not pre-register for the expo?
A. Then you must bring some printed show material to the show, or you will be charged the on-site expo only registration fee ($45) in order to register on-site. If you pre-register, or bring show material with you, on-site registration is FREE for qualified registrants. Online registration is available throughout show days.
