eBay-like user store
We have recently purchased ClassiPress and we are at the very early stages of customization.
My client wants to have some kind of feature that allows user stores like eBay has, where users have their own store within the site with all of their items for sale within the store and the site,
Is it possible to replicate that eBay feature? I am a Web Developer, so I don't mind tweaking the code.
