I really like the idea of the website. I signed up and started to make a kit, but when I wanted to add my favourite bag to a kit (Tom Bihn Tristar), the site can't add it. I provide the link to the Tom Bihn website, as they only sell direct and not through third-parties, but it doesn't work.

This makes the site far less useful to me, and makes me think what other things am I missing out on that others couldn't post to their kits...
