As I was looking over the site I was thinking - I know you're just getting started but there is a real lack of plants. And then I got to thinking why can't I sell my plants on DoLeaf? Just my two cents - but what about making a "sell your plants" section?

edit: I found your "Sell With Us" link. But I guess I was thinking more of - any could sell a plant - that might help you get a larger selection. But I guess there are issues with that model.
