I'm going to do my own research on this anyways, but I was wondering if anyone could point me in the direction to a list of the bigger UFO conferences/conventions coming up this year or next?

Also, how do they select the speakers for these events? Is that done through agents and such or can you just call up the coordinator/organizer and represent yourself? Self publishing seems to have gotten rid of the need for agents, managers, traditional publishing houses. So, I'm wondering if that new model is permeating other avenues of distribution of information?
