the best subtitles website till now is www.subscene.com, and i bet there are alot who really want this site implemented in boxee as an alternative to opensubtitles.org
so LETS GET SUBSCENE FOR BOXEE !!!
There are lots of subtitle DB's in the net and the one I'm telling doesn't have the best
search engine in the world but it does have most subtitles I could find on a subtitles site. Just go and check for it.
