This site is a great place for creepypasta and there are quite a few gems in it (though some are lackluster).

My favorite creepypasta is one I can't find right now because the site on which it's on (which isn't the site I linked to) seems to be down, every link sends me to a site with the story of Candle Cove.

Well, aside from that one I also liked these a lot:

There are a few others but I just can't remember what they were called ^^;.
