We have changed our commenting system to a new platform, called Gigya, which requires you to register on this site.
You can register using a username and password, or you can use a social media login (eg facebook) to comment. This will allow you to easily share your comments to your social media accounts if you wish. If you don't want to, you can un-tick the box to prevent that comment from being shared to your facebook or twitter page.
You have the option of commenting as yourself or using a nickname if you prefer by going to the profile section and adding a nickname.
We hope you like the change. We'd love to hear your feedback here.
