I don't seem to be able to register for the eBay sandbox, or the developer program. I have tried multiple browsers. Can't believe how buggy it is. 1) The eBay sandbox gives me an error 500 when I click register. 2) The form to register on the developer site keeps refreshing as I fill it out stopping me getting any further. This means I have no way of creating a test seller account or signing up as a developer.
