I just have to say that doing it GB's way (when there is a problem with a thread) works. Here's my experience:
I was following the "SWAT teams are worthless" thread, and Tippie locked it. Now, I could have made a post whinning "Why was this locked? You stupid (bleep)(bleep)(bleeping) moderators are nazis!", etc, etc. Instead, I emailed Tippie, explained my position, and asked him nicely to unlock it. He did, on certain conditions though.
That is how things should work. If you have a problem with a thread being locked, send an email to the mod who locked it. Ask why it was locked and if you want, explain to him in a nice, calm fashion why you think it should be unlocked. Regardless of whether he unlocks it or not, he'll give you why it was locked. This serves to find temper emotions, and stops people from jumping to the wrong conclusions. It also keeps things a little less crazy around here. Don't jump the cuff, and yelling and calling names only serves to solidify there position. And you may understand why it was locked, and may even agree with it. We need to be more friendly around here.

Forgot to say Here's to Tippie!
