Thank you for asking!!
New members without 5 posts need to contact an admin to have their accounts deleted.
For reference, new members need 5 posts in order to have access to their profile/accounts settings.
Let me know if you'd like your account deleted. I can help with that.
✽ If you have more than 5 posts, go to the Home menu, mouse over the world Profile and click Account Settings.
Mouse over the Word Actions and select Delete this Account. It will ask for confirmation. After you confirm. Your account will be deleted. If you have posts, they will either be deleted, or be guest posts.
