Are you interested in becoming an administrator on a wiki?
If so, please first check whether the wiki's admins are active. If they are active, you may need to wait until a new admin is needed.
In the meantime please make sure to get to know the community by editing the wiki and reading any existing policy pages. When you are an established member of the community, you may be invited to be an admin!
You can also try leaving a message for an active admin to let them know you are interested in helping out. Bigger communities often have request pages or nomination pages for this, but on smaller communities you can usually just approach an active admin on their Message Wall or User talk page.
If the wiki's admins are not active, you can ask to "adopt" the wiki. You can read about how this process works (including what you need to do to be eligible for adoption) on Help:Adopting a community.
Note: if there's an active user community on the wiki, please start a discussion with that community about who would be the best admins, and why you would like to become an admin. Please provide a link to this discussion on the adoption request page, which will make it easy for Fandom staff to give the rights to the user(s) that the community agrees on.
