I've just put myself on the list and my feedback so far is that the format of booking is a bit confusing. I'm available any time during the day but I have to choose a 15 minute slot. What happens if too many people have chosen this slot as well, but there are some other under-booked slots available?<p>I think a more straightforward way is to just list yourself a give a preferred time, and then the VCs decide who they want to see when. If this 15 minute slots are meant to be used then it's fine.
