I visited the demo store but didn't see much. I was hoping to be able to interact with it as an administrator/merchant and a buyer. Also, I was hoping I could see the Import file feature so I can be sure that my merchants will have no trouble doing this.
It would also be nice to see the different themes. I really like the way dnnskin.com did theirs and so I'm hoping this is one of the themes offered.
Can you beef up the demo store to showcase some of the features you're modules offer?
