When I search for "Durarara" on SideReel, I do find your page. I also find a second page for Durarara!! with slightly more content.
As for "how to make it an anime page," what do you mean? Do you want it to be tagged anime, or do you want it to show up on the Anime home page? Right now, I am leaning toward gathering the information from your page, then turning sidereel.com/Durarara!! into a redirect to the existing /Durarara page. That will avoid duplicating our efforts.
