Some users have large signatures or sigs with images. When scrolling through a long topic, you may see that user's sig several times. It would be nice to have a configuration setting that would limit users' signatures to be displayed only once per topic.

Hmm, interesting idea... Worth adding at some point.

Once a page would be good instead of once per topic - long topic can split into many pages. I limit 5 post per pages due to performance reasons on long posts.
