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!
