The<unk>  dialog allows you to personalize some aspects of a MediaWiki wiki. They will apply only when you are logged in. The default wiki sysop admin login name is: WikiSysop.
Some MediaWiki projects form a family in the sense that one logs in into the family as a whole, and that common<unk> settings apply. Notably this is the case for the more than 1000  Wikia projects. On Wikimedia projects logging in and setting<unk>  are currently done separately on each wiki. You may find it convenient to specify the same<unk>  on each wiki that you use, but this is not necessary. See also Single signon transition.
