This was a feature that was asked for really early on. I'd like to only show threads from certain boards on my home page. Prime example: The Memes and Games board comprises about half of the home page. Sure those threads can be funny, but I really don't care about them and I'm really tired of having them pushed into my face every time I hop on the forums.
I would reccommend you download the Forum Enhancer Kit, or F.E.K. It allows you to set custom avatars, blacklist people, customize which boards you see, and see the number of upvotes and downvotes (as opposed to just the net total). It is perfectly safe (even some rioters use it), and downloads/installs in a few seconds. I personally have found the boards to be far more enjoyable since I got it. http://boards.na.leagueoflegends.com/en/c/miscellaneous/3V6I7JvK
Hope this helps. http://rs200.pbsrc.com/albums/aa101/PattyPruePiper/Gifs/tumblr_leacb7GQam1qcwsd8o1_400.gif~c200
