IMVU is an online "3D chat and dress up community," according to the game's website. IMVU players must create an account on the IMVU website, and then download the IMVU program. You cannot delete your IMVU account within the IMVU program. Instead, you'll need to access your account page on the website. If you are sure you no longer want to play IMVU, consider uninstalling the game inside the Windows "Add or Remove Programs" feature inside the Control Panel.
Visit the IMVU website, and click "Member Login." Sign in to your account with your username and password.
Click "Account" on the top bar. Click on "Help."
Click on "How Do I Delete My Account?" Click on the "Delete Account" link. Alternatively you can access the "Delete Account" page.
Enter your account password. Click "Continue." You'll land on the confirmation page, which lets you know your account was deleted.
