btw I'm aiming for 500 points so I can reach a new rank. If y'all could help me that'd be great! I currently have 255 (before posting this question), which means I need 245 more points. After posting this question, I should need 255 more points (I think, Idk I'm not good at math).
I also don't even know if this is the right category.
