Hey, I am LevelUp and I have a super cool level system which you can configure yourself.
I support 3 different languages (English, German, French) and I am based on slash commands (/). In my level system you can get xp by voice channel activity and/or by messages. You can set many things, for example if you should get xp per minute or per message, if xp should be counted when you are deafened and/or muted or the content of the level up message, you can also customize many other things.
I would be happy if you invite me to your server and I could be your level system in the future!
