Hello! Help pages on Community Central are generally managed by FANDOM staff. Please don't update images simply for the sake of using one from your own wiki. We are happy with the current example image and it does not need to change. Thanks!
Heya :) I recently deleted your question, but only because it was sorta in the wrong place. Pages that begin with Help: aren't actually for questions. They're places for help files—essentially the manual for using FANDOM.
I noticed your blog post but you didn't have the comments enabled. To make someone an admin, simply go to <your wiki name>.wikia.com/wiki/Special:UserRights, enter their username, check the administrator box, and save your changes. I hope you're a bureaucrat, becuase those are the only people who can make someone an admin (not including FANDOM Staff).
