As part of our ongoing improvements coupled with an effort to decrease spam in our community, we’ve begun to decouple forums accounts from Xamarin’s single sign-on account system. Previous posts, achievements, and other forums activity history remain the same. As the changes roll out, you'll need to reset your password before logging in. If you're already logged in, you should be able to stay logged in until your login cookie expires (and I'd recommend this!).
Over the next couple of days, you may see intermittent periods where you'll be unable to log in. If you get caught during one of these times, I'd like to apologize in advance for the inconvenience and request that you try your login again a little later.
Thanks in advance for your understanding as we work to make the forums a better place. Please reach out to me via accounts at xamarin.com if you have any trouble moving forward.
