We're currently looking for volunteers on the new RailsCart
project. The idea is to build something relatively simple with all of
the features that most open source shopping carts seem to be missing.
We'll be using ActiveMerchant for all of our payment gateway needs.
We're not trying to build the ultimate shopping cart. This is
designed for Rails developers who need to slide a shopping cart into
their websites. The project is still evolving so feel free to drop by
our mailing list and contribute to the discussion. Some of our
contributors are tied up with outside work so we could use an infusion
of coding talent.
