@pumaspread, these presentations will be archived pretty much immediately following their conclusion. So, you can hear the archive anytime after the live session is over. Presentation materials should be downloadable before the presentation starts (and thereafter, of course).
I'm told that even if you cannot make the live session, you can still get credit for attending (and qualify for a board) if you view the archive promptly. Once the shipping list gets generated, though, that opportunity closes. Not certain of the timing, so if you cannot make the live session view the archive as soon as possible thereafter. Oh, and you must attend both of the first two sessions to be able to get a board for the remaining three.
