As the title says I'm curious to know what the user rankings are for, I just registered and I'm getting to know the site and its features.

I have 20 points, is it right that I earn points by simply posting?

Yes, that's right, by default it "auto-votes" your own post, so simply by posting and commenting you can earn points even if you don't have highly voted posts like @revepg 😛

Hahaha, on my way to reach the 400 points milestone 🫡
