You read correctly. Once an account is deleted, you need to just create a new one. However, we can make arrangements to get old game ID's back, if it is available.
Just create the new account, and if the game ID is not available, send an email to
support@hitechcreations.com requesting the old game ID back.
Be sure to include the new login ID for the new account and note you are aware that you will lose all scores, squad associations, and perk points when this happens.
