For our April community-brigade event, we'll be getting together and actually building a real app that solves a real civic need. But don't let the word 'app' scare you away. As long as you can use a spreadsheet, you can contribute in a meaningful way to the project. And, even if you can't use a spreadsheet, you can still help by offering personal insight and your own local contacts and knowledge. If we do it right, we'll have a working product to show by the end of the evening.
