Disambiguation Links Hi Evilbu What I changed on the Quadric projective geometry page was simply an incorrectly directed link to a disambiguation page The link to field had been linking to field which is the disambiguation page for the word field but I changed it to link to the correct page field mathematics What you went to when you clicked on the you can help link should have taken you to Wikipedia Disambiguation pages with links which is a wiki fixup project The project works to fix all wikilinks that link to disambiguation pages and instead have the links link the specific article that they refer to Let me know if you have any other questions and I hope you continue contributing to Wikipedia a
