Hi, im currently making a Character Level and Craftling level System,
and i would like to know what you think and if you got any ideas of any changes or adds to this script?

Current Features:
-You can freely give and take levels with the admin menu.
-Saved with MySql
-No known bugs
-Each level require higher amount of Exp. Scaled by 30% ish(Rounded)
-All in Lua
-The Exp required automaticly adapt if you give or take levels from a player
-Currently max level: 20
-Easy to add to other scripts if more features are wanted once its done, little
knowledge in lua is required.
-Give/Take can be moderated by permissions easily
-You gain crafting Exp everytime you make a craft.
-The higher crafting level you are the more and better things you can unlock to craft.
Unlocks:

Lvl 2: WEAPON_BAT
Lvl 3: WEAPON_GOLFCLUB
Lvl 4: WEAPON_MACHETE
