∞ Yahoo! takes a step back in the new Groups
From the Yahoo! group blog:
Based on your feedback, we are going to iterate on the new design separately from the original Groups product. For those who are interested in using the new design, we are creating a whitelist (instructions forthcoming in a blog post next week) where you can sign up for the option to use the new design. There are two things to note about this whitelist: (1) you can revert back to your original groups experience any time and (2) we may ask you for some feedback so we can continue to improve the user experience.
