i'm not sure if this is already being done, but now that the club is getting all these big-name speakers, i wonder if it would make sense to videotape them and put the talks online, the same way those canadians did with reefvideos.com (e.g., with Anthony Calfo)... if there is some concern about security/privacy, the videos could go in the members-only part of the CTARS site.

p.s. we could also consider the 'virtual tank tours', too....
