Pipeline [is] a space where we [can] share designs with you, and you with us. A space where you can find the latest ideas, discuss/rate them, and even be notified when they become Generate products (at a special pipeline discount, of course). We’ve even made it super easy for you to add your own designs, and see what people think of them. (If you submission becomes a Generate product, you can have it at our cost).
The service is available in both English and Japanese.
