When you create a post bar, you will receive an invitation letter (please check the system notification by computer), click the link in the letter to fill in all the information, and become the internship bar owners of the post bar.

A trainee bar owner has the same rights as a regular bar owner, except that it cannot approve a second bar owner. Stick to posting 3 or 5 posts every day, and you will become a formal bar owners in 30 days. I don't often post during my internship, and I was dismissed after 30 days.
