Have people noticed the new Beta Customize Area?
I've been playing around with it for that last hour. It's much easier to use than the old customization. And there seem to be lot more themes to chose from. Not all the themes have the same customization options though.
I was finally able to return my LJ to it's original scheme...and it works!
Maybe the LJ people were playing around with it while readying this beta and that's what messed it up before...
