Big Idea almost has enough presenters to work

I want to keep my one day conference small so I can manage it properly. Right now I have heard from nine people expressing an interest in venturing to Arivaca to present papers. That would work out to three panels with three papers each. Strangely, even though I expected alot of proposals on Latin American immigration into the US, I have only received one. I have gotten four proposals for topics related to immigration into the European Union. I just got two proposals from European universities this morning. I think I am going to cap the number of presentations at 15. I want there to be time to discuss all of them in a single day without too much of a rush.
