Go into Profile > Modify Profile > Look and Layout, and the first thing on the list is "change" the theme from Green Bean to something you like. I use "Concrete".
Thanks OP, I'm one of those people who doesn't like changes unless I'm asked, It seems like we are loosing more and more control over our lives today, stuff like this drives me nuts, I turned on the The Weather Channel first thing this morning to check the local weather, the Weather channel has a feature where you push a red button on your remote and it reads your zip and gives you your local weather.
This morning their was one little problem, The Weather Channel doesn't exist any more, it's now Weather National, and it doesn't do that.

Then I go to B&B and the whole screen is changed.

And if that's not bad enough, I'm writing this post and I go to the smiley selection, guess what, that's mucked up too, I friggin' give up, Jeeze, if it ain't broke, don't fix it.

Now I preview my post and do I see smileys, no, I see little red friggin' X's, where's my Absolute !
