Hey! There's many things that you can do to level up! For me since I'm not that good at creating my own mods or texture packs or CIT's...Personally I just comment positive messages on other peoples posts, like keep up the great work, or you're doing great, or I luv it!...Anyways, I hope you find this message helpful! it's taken me some time but I got to lvl 15, just by using this method! Hope you have a great day!
