Hi, I'm just getting started with multisite and will be building a website for individual product brands. They will have categories, for instance, kitchen. On the main site, I'd like to feature a grid image layout of all the products in the kitchen category. I can specify to the kitchen product owners that each product should be tagged "Kitchen" and have an image, 200x200, that should be named "ProductAvatar". Would the tag feed, or another plugin help me build this? Is there documentation to help get started?
