Ehren is a great individual to work with. He does whatever he can to help, and does tremendous work. Not only does he work to provide top notch themes for IPBoard, he keeps them updated constantly. We made a mistake of going with another theme designer when we updated to 4.X, and it was someone which we haven't used in the past. Well that was a mistake, which is why we went back to Ehrens Themes.
He's one of the handful of 3rd party developers here that I truly trust and appreciate. You definitely won't be disappointed with his work or support.
