David Colarusso’s QnA is a really simple, easy-to-use question-and-answer tool for lawyers. You can even use it as a basic document assembly tool. It’s free, and you can see it in action on the Massachusetts public defender’s website. Get the code on GitHub.
It looks like a pretty great tool for helping people find information or forms on a website, but also for web-based client intake or even simple legal advice (assuming you can do that in a simple Q&A format).
