The majority of you will be aware that there’s been a whole heap of problems with the WordPress commenting system as of late. Previously those who had a Gravatar or tried to post anonymously (without putting in an email address or username) were greeted with an error message saying the email they were using is associated with another WordPress account.
According to the WordPress staff the situation has been resolved. Those of you who are trying to log in with your Gravatar/Avatar need to visit WordPress.com or Gravatar.com and log in with your details and you should be able to post under your username with your personal avatar. I really hope it works this time around! Please let me know in the comments if it actually works.
