Well, since you're so interested in improving PF (which is awesome!), I have two things which I currently hate: 1) When one is not logged in, whenever one copies something from PF, we get a message "Read more: https://www.physicsforums.com"... I hate that and it pisses me off! I don't think anyone likes that.. I don't think there's any reason to have this "feature". One already knows about PF, since one is copying something from the site. It's also very easy to delete, so it's not going to avoid copying content and not mentioning PF. So it's basically a nuisance. 2) When log-in in PF, the "Log-in with Facebook" is much bigger and draws way more attention than the normal "Log in"... I hate this.
