Oh yes, we started doing the pre registration thanks to the software we made and crossing that with people that reserved t-shirts to have an amount of expected people that you know will be there, but it is open to everyone and we always expect "unexpected" people.

The catering was more to the volunteers and speakers so we knew (almost correct) how much people will eat. I cannot remember if we made something like "meal reservstion". We had coffee.

I'm doing another event (megagames) snd there you must pay in advance and that is the catch to be sure you are not saying: I'm going, and you not. Also, we don't make money from that, it is used to run the events and pay the costs to develop a megagame (prints mostly)
