There is a fellow at trekbbs.com calling himself CaptainBearclaw who has been doing research on deleted scenes from the Star Trek films. I already have linked to his thread over there. Matter of fact, he is also a recent member here, calling himself Tack. He just started up a blog on these deleted scenes.

Now the blog hasn't gotten too far yet, but his thread is pretty thorough, and I imagine his blog could become much like T-bone's Star Wars site if he keeps at it, given the material already in the trekbbs thread. Check this blog frequently. I know I will :)
