Presenting at Conferences

I've been thinking lately that I'd like to try presenting at a conference or two next year. There are a few scheduled that I should be able to attend:

1. Colorado TELECOOP, April 16-18, Breckenridge (proposals due January 26)
2. Colorado Community College Conference on Composition, April 18, Greeley (proposals due January 31)
3. Teaching with Technology Idea Exchange 2008, June 5-6, Orem, Utah (proposals due Feburary 1)

Obviously, I'll have to choose between the TELECOOP Conference and the 5Cs. Why did they have to schedule them at the same time?
