@dennismsmith Hi - as well as enabling the stock reputation system, I am usingnodebb-plugin-reputation-rules nodebb-plugin-user-level
For the leaderboard, you could usenodebb-plugin-leaderboard
I personally do not use this, but it's there.
If I want to change(visual, UX, and place) just one button, Ex:
Should I create another template/theme? Or it could be done with plugin?
@Nicolas For small one-off changes like this, consider using the "Custom CSS" screen in the ACP. This doesn't help if you want to move the button around, so if you're looking for more in-depth changes, you'll have to consider creating your own theme.
