I agree, we should be flexible & see what comes out of the call for content - but we have time & space limits which we should be aware of. Let's say we're working with 40 minute presentations, with 5 minutes break between each one, and a half an hour morning break and half an hour afternoon break, and a 1.5 hour lunch. You end up with 09:00 - 09:45: Presentation 1 09:45 - 10:30: Presentation 2 10:30 - 11:00: BREAK 11:00 - 11:45: Presentation 3 11:45 - 12:30: Presentation 4 12:30 - 14:00: LUNCH 14:00 - 14:45: Presentation 5 14:45 - 15:30: Presentation 6 15:30 - 16:00: BREAK 16:00 - 16:45: Presentation 7 16:45 - 17:30: Presentation 8 End of day So we have 24 presentation slots per day, max. Cheers, Dave.
