Hi there, you successfully authenticate with Twitter, now it’s going to be easy to login using single signin. While we are booting your playground for building your lists, we recommend you share your email address with us and agree to our terms of service. We will send you a confirmation email with a password to use if for any reason your twitter account can’t be used.
If you agree we will also send you updates on this product. We start with simple list building but expect many new interesting features in coming months.
