A wiki to the rescue?

At our library we just sponsored our second (annual?) event where we recognize and thank all the people and organizations that make our community a great place to live. This year finding the best times when most of the planning committee could meet seemed to be especially challenging. I'm thinking that using a wiki might help! Ideas could be added to the wiki, people could suggest "tweaks" to those ideas, and for those members who are unable to attend a particular meeting there would be an interactive place to still add input and see what was accomplished at the meeting.
