What a fantastic tool to make it super-easy to gather data about the people joining your Facebook group! The only difficult thing about it is setting it up; I didn't find the instructions terribly helpful. Luckily, this was recommended by a friend, so my friend helped me with set-up questions. What it does is gather potential group members information, including answers to member questions, into a Google Doc. I'm using it to help me better understand what people want from my group so I can deliver value. I have plans for several Facebook groups in the works. I will be using Group Collector for every one!
