Anyone can sign up, it's totally free, and all we ask is that you provide us with feedback about the feature. We'll use your feedback to decide if we want to proceed with this feature, and to improve it's usability.
Fill out this form (it's easy) and we will create a token for your site that will unlock these new features for the next 6 weeks.
If you want to know more about our experimentation process, visit https://bit.ly/OriginTrials for lots and lots of information.
We also plan to maintain a low-volume announcement mailing list for each experimental feature. When you sign up for access to a feature, we'll add the email address you give us here to that list.
