Great way to gather info

I stumbled upon an ingenious way to gather up information, whether it's from your friends, for a little homemade survey but I was mainly picturing the painful task of gathering information form other homeschoolers to plan your field trips, co-op classes and other stuff. I mean, coordinating everyone's schedule can be a pain in the rear end and another difficult task we find ourselves doing is trying to gather up votes about who wants to do which classes at a co-op. I remember one year we had it down to a science for our science club, but one year we had a bunch of members move away and one lady's daughters started a dance class during that time and it just ended up being a big headache to try and get everyone's schedules coordinated enough to come up with a planning meeting, so having a website for making surveys, along with easy to use survey templates would probably have made a big difference. Maybe we will use one this year. What about you? What do you use for group planning? have you ever considered using a website that helps you gather information? it seems to be a really great application of technology.
