No, it's not absolutely necessary, but you'll be missing out on one of the best parts of People Like Us. People Like Us is all about community, about sharing, talking to each other, communication. The PLU platform is used for direct messaging, enquiries and discussion of exchanges, but community discussion happens in our Facebook group. It's where the personality of our community really shines. All important communication is emailed via our Blog, and votes take place in both Facebook and on the platform.
