I'm pretty new to coding in general. So my apologies in advance for the questions (3 at the moment)...
1. I'm looking to sell only downloadable products. What is the storage limit? I know the per-file max is 250MB, but is there an overall storage limit per store/account?
2. Can any other attributes be added to products? I need to be able to track sales by contributor; so is there any way that I can add, say, a userid to the product?
3. Still a little unclear on how each product's link is generated. So my store is melapix.foxycart.com, and I have a product in the images category with code cd0001. Would the add-to-cart link be melapix.foxycart.com/cart?category=images&code=cd0001 ??
