Install the PT-BR translation - Portuguese from Brazil ([login to view URL]) 3. Install a Paypal shopping cart - ([login to view URL]) 4. I need a second payment method "Pagseguro" from Brazil - ([login to view URL]) 5. Insert a Paypay "Donate" button Note: I don't need a standard ecommerce, with products list, categories, etc. I'll have a few posts with some products and I need to be able to add a "Add to Cart" button, and a simple cart manager.
