Does anyone has any idea as to how to add a new tab to the existing tabs (article,discussion,edit and history) to the wikipedia page.I have the mediawiki installed and the database dump imported. Now i wana tweak and make additions to wikipedia. I have very little idea of php but am ready to learn the advance concepts as the need may arise.
You make additions to Wikipedia at http://wikipedia.org. Don't call your site Wikipedia, or you would be violating trademark law.
That said, have a look at Magnus Manske's validation feature; it adds a new tab, 'validate', to every page.
