Ok this might sound awfully picky but I'm a lazy person...
Whenever I click a forum thread, in any forum, to show the actual posts, the page scrolls down to the first anchor so we don't have to see the big logo header and stuff like that. Unfortunately, it scrolls down a bit too far, cutting out the opening poster's name at the top left of the opening post.
...so, I have to scroll up a bit so I can actually read the name of the opening poster while I read his/her post! I guess part of this is because I have both avatars and signatures disabled so I won't see the poster's name in any of those, but they're useless information to me and just adds to the clutter so I prefer to have them disabled ^^
Using IE 6 SP2 something something... here's a screenshot showing with the "problem":
