Manual:User signatures

Users can sign their comments using the wikitext ~~~~ and some other variants; Help:Signatures explains this in more detail. The signature code is replaced by an actual signature during the pre-save transforms.

CustomizationEdit

A number of system messages can be used to customize signatures in some context or another:

Most editing tools provide a button for adding a signature; this is usually limited to talk namespaces. Most editing tools respect $wgExtraSignatureNamespaces which can be used to enable signature buttons on some non-talk namespaces as well. (The signature wikicode itself works in all namespaces.) Some tools also enable the signature button on pages with the __NEWSECTIONLINK__ magic word.
