Well, you could always create an account for your sub-par fic, I guess. I know it's not all in one place, but I know that for this one site, I kept all my old fics on this one account and moved the ones that I liked onto another. I wrote for Harry Potter mostly ages 11-14, so some of my fics are bad

Also, that moodtheme is hilarious! But I know what you mean about LJ not having some moods that they should. I usually pic a moodtheme pic that works, and then put what I want to put in the box next to it. Silly LJ!
