All I do is post as normal and the points are applied automatically. If I had to do something to switch that on, I can't remember. But it's important to post at https://snapie.io and not in any other Hive frontend.
So, do they only count post or comments too? I was using their frontend before but my name was still not showing in the leaderboard.
They count just about everything. Including the vote I just gave you. Sorry it isn't worth anything so I don't usually vote here.
When you say that you used it before, when do you mean? The #snapie points system is quite new.
