Gutenberg: Official Call For Testing

Gutenberg is now in beta, with that comes a new opportunity for testing. There is now a testing page dedicated to Gutenberg, you can find it right here. There are currently 2 types of testing being looked for, each has a central feedback form.
Looking for other ways to give feedback? You can also write a blog post (let the editor team know about that in Slack #core-editor) or add an issue to the GitHub repository.
Your feedback and testing is really important at this stage of Gutenberg, it really does matter and help make this as good as it can be.
