This is a tiny project compared to the previous one, which was big and had complex logic. This is more like a "break" project for me.
The concept is based on a common problem: every group of friends struggles to decide what to do or what to watch next.
This website solves that problem. How?
Everyone joins a room, then each person submits a concept (idea), and finally, the system selects one at random.
There's also another mode: everyone submits a concept, then votes on the others’ (except their own), and the concept with the most votes wins.
