`  == Bug 5645 ==  Saw this bug report over the signature button appearing in namespaces that editor's would rather it didn't and figured I should mention the ``obvious``  Just add   'filters': [ 'body.ns-talk, body.ns-4' ], to the signature button's entry in jquery.wikiEditor.toolbar.config.js and your done. The same approach is used for the references button (see that same .js file if you don't believe me)If you want to allow the signature button's generation in more namespaces, just add their numeric designation(s) to the filter using body.ns-4 in the above as your example (no comma after the last entry btw).  You can also exclude button generation for certain namespaces this way....   'filters': [ 'body:not(.ns-2, .ns-8, .ns-828)' ],  Hope that helps    `
