I have been playing with the new theme by ElegantThemes
TheCorporationTheme
http://myeasyhosting.mobi/
I have to say this certainly comes up to scratch as a corporate style all business no nonsense theme.
The styling is totally business, the menu design is excellent, its one of those menus that you add categories to, just so you can play with it, running your mouse cursor up and down the menu watching the bevel rise and fall.
I know its a bit sad but seriously try it you'll soon get what I mean.
I'm using eNews at the moment on most of my sites, but I may find my self changing to TheCorporationTheme, it really is very effective with plenty of options.
There are plenty of ET advertising widgets plus different theme colour options and much more.
This theme definitely seems to be the most business like and aesthetically pleasing theme I've seen by ElegantThemes.
Keep up the good work ElegantThemes.
