[SOLVED] Do NOT Succeed to enter as ADMIN
What kind of "admin menu" are looking for? By default, the only menu that points to Special:ListUsers is Special:SpecialPages. You can get to that page from the menu on the left, and the link to the user list is in the "Users and rights" section.
The Admin Links extension provides an easily accessible "admin links" page, and one of those links is the user list. Is that what you're looking for?
I have no any Special:ListUsers nor Special:SpecialPages on any menu on the left.... and logically no "Users and rights" section nowhere...
Special:SpecialPages is listed as "Special pages" in the "Toolbox" section of the left bar on every page.
Cheers ! Finally FOUND... but I entred to special pages, without being logged in and at the botom of the Special Pages there is the section Othre Pages and appear the Admin Links... is it not to be private ONLY to the sysop or administrator of the wiki ? Everyone can admin the mediawiki ?
Admin Links merely provides links to existing functions; it performs no actions of its own. If you try to perform an admin-only action like editing system messages without having the required rights, MediaWiki will still prevent you from doing it. Admin Links is simply a convenience tool to make things easier for the wiki's administrators.
For normal users, Special:SpecialPages is the only place they'll find a link to the page; not because it's too powerful, but simply because it's not very useful for normal users. The restricted functionality is already restricted.
