Okay, so to finish up on that last post I made, here is a list of all the layout journals that I think are worth your time:

I might add to this post later. Basically, if you want to find an icon for a certain series/fandom/celebrity, let me know and I can probably hunt down a journal that posts them. ;D
Oh yes, and if you found any of this helpful, do comment. It took some work to compile this list, and I'd like to know if anyone found my urge to make lists useful.
EDIT: This entry will be periodically updated as I come across new places that are perfect for tweaking and enhancing your LiveJournal experience. (Wow, I sound like I'm advertising for LJ.)
