Purchased the Schema theme.
I was sold on buying it the first time I saw it... I also use Studiopress and was about to use it on a site I'm doing but Schema had far more options to customize the theme built into the themes core.
Also own Thesis... but like Studiopress, you have to get under the hood if you plan on doing much customizing.
Had an issue (and it was my own fault) - the ad was not showing up after the post. I later discovered (not told them yet) that I was running adblock plus on my browser - so ads don't show.
Support logged in to my site - took a look around and did it all quickly.
Thanks... really liking Schema.
