It depends on the situation. This is what the admins have in mind to create an new admin on The Vampire Diaries & Originals Wiki.
Helping to report problems and improper actions of trolls / vulgar / immature users, admins.
Edit constantly, but in the right way, clean and safe. You do not have to edit just to get points or to get the attention of other users.
Understand and heed the messages / warnings from admins when you have caused a problem.
You do not have to cause problems or make vulgar or hateful comments to other users (registered and anonymous). Just as you should not delete information, categories, images, etc.., The pages just to have more edits.
And above all, if you prove to be a good user, you have to known from TV series and has been on wiki for some time and made good things, and helped other users, you may be able to be promoted.
