As a kommunity organizer you can remove your kommunity. If for some reason you've decided to do:
1- Go to your kommunity page that you want to remove
2- Click on the gear icon on the right
3- Click "Remove kommunity"
4- Click on "Yes, remove" in order to approve your action
After that, your kommunity will be removed, but you can always create a new one.
Keep in mind that a removed kommunity cannot be retrieved.
