If a mod is bored enough to take this suggestion, I think it would be worthwhile. I've seen this on other forums where once a user has posted in a thread and he posts again the signature will only show up in the first post per thread.
I know there's an option to turn signatures off, but I like seeing peoples signature at least once. It's simply a waste of space after that.
