Hm, actually I don't think it's a good idea. While we don't encourage multiple repping, this might actually turn out another 'thanks' orgy we see in other threads. Thanks are largely used in the download sections where they serve a purpose. In threads where everyone can thank everyone else, there was overuse of the thanks button at times, that's why the button was removed from some sections in the first place. People might use it as another way to boost their rep, and some people did.
So... where's the 'no' option? (I know, I hate this question too )
