@SW8573:

If you add something as  to the Custom signature line in Special:Preferences, it will be replaced by   automatically. This means, that  will not add   text, but the content of this page. That is why most of the people use two different signature pages, one with the signature itself (for example  page) and other with link to this page (for example   page). Then, if you add  to the Custom signature line in Special:Preferences,   will create   text.
