It may be that the rest of the site is like this as well, I just happened to notice it on the WoW Guides category page.
Is there any way it can be coded to ignore "A" or "The" at the beginning of a page name?
As an example: "A paladin's Buide to uncrush" is listed under "A". Technically that's the case but in most indexing (and I mean that in the severe-bunned, sensible-shoed librarian sort of way, not the technology sort of way) ignores these sorts of terms because they're really not meaningful for someone looking to find something.
