Try alternate search words in Google and the other SEs, like "forum directory", "forum directories" and add +sports. That should help shorten the results, because what you really need is a directory, not just a list of sites with the term "sports forum" - that can include everything from an actual sports forum to an article that mentions it. Think about the meaning - a forum can be an arena - as in the sports arena or sports colliseum. All those unwanted results will come up, burying what you really want. Sylvia
If you are interested to have HQ pictures, images, photos, wallpapers etc etc about sport take a look at http://sportgfx.com
Google search for sport forums would give you answer. or Directories of sports forums may help you in this regard.
