I'm not crazy about the white background. It causes all new problems with seeing some text that I had already compensated for with the black background. I found how to send PMs, but there is still a steep learning curve. Will have to see how things change once Avery gets someone to change some of these things.......hopefully soon.
I used to prefer the dark background scheme as well, but with the larger font and decent contrast i don't mind the current light layout as much as i did the the old one. It would be nice to have it as an option though
One thing i noticed: It doesn't seem to keep me logged in even when i check the box for that, i never had any problems with that before. I doubt it's related to layout per se, but pretty annoying.
