Forum:How to make a wiki for users only?

I have an annoying spammer in my wiki and I hate always locking my pages. Is it possible to make that only registered users can add and edit all pages?
 * You can ask the Staff to disable editing for anons, but it is generally recommended to block any and all spammers. If you haven't done so already, block him. Savannah   Star  17:41, November 3, 2012 (UTC)


 * He somehow gets back with different IPs,but ok, I will ask the staff.


 * Then he/she can create a new account. Just sayin. Just block every time. voice (talk) 16:00, November 5, 2012 (UTC)


 * Staff will refuse to lock your Wiki to anonymous users for anything longer than a week, for obvious "open-community" reasons. Applying with staff for it is a temporary option for any Wiki admin. -- ~ Mana ~   (Talk)   16:30, November 5, 2012 (UTC)


 * Hello! Its me jonah! You can tell admins to block and protect the pages for infinte


 * Late reply, but for future people looking: you can use Wiki Features (as an admin) to require all contributors to log in. 14:50, 20 February 2021 (UTC)
