NOoooooooooo ... mama take me deep again
How do you promote someone to SA?

I dunno for sure but I think the person being promoted has to have some sort of membership to be an SA. Even a gold would do probably

Go to the where the members section of the club, search and find user you want, then got to the section of where you can change their status, and promote to SA. Although has to be a paid or current free trial member to be an SA.

Do I have to enter the payment method for free trial tho?
Think so, all though, it won't charge right away. Also if you cancel the re-charge you will still have the free time.

Although once you are SA, you don't have to be listed as a paid member to keep the SA. Only to become one.
I'm a SA myself Super Administrator, thanks guys and gals
