Thanks for tinkering with the styles, it is nice to have options.
I guess you probably realize that the two newer options do not have the EN World logo, or the banner ad.
I'm not sure I like the boxes that Silver and Exposed use around posts. I prefer simple, easier to scroll along with less wasted space. The "Light" style would be my favorite if I could read the yellow text.
