 Once on the draft version of this page, look at the top right corner: you will see three icons, an arrow, an eye and a note-pad. Clicking on the arrow will open the extension and allow you to view the annotations. Create an account and log in if you would like to reply or make your own annotations. You can also highlight text, but this is not publicly visible, it is only for your own reference.

 Note that the annotations are only visible for the page that you are currently viewing. You can see all the Annotations on a website by opening the "Public" menu at the top of the dialog pane, selecting "Public" again in the drop-down, then "View group activity."

+As an alternative to activating this for everyone, you can also advise your students to use the [hypothesis browser extension](https://web.hypothes.is/start/). In this way, students are not distracted by potential unnecessary public annotation and comments by fellow students and teachers.

+# Discussions in your book: Utterances
+
+[Utterances 🔮](https://utteranc.es/) is a lightweight open-source widget which allows you, your colleages and your students to discuss stuff in a blog post in your book. It is build on GitHub issues, so requires a GitHub repository, although the book can be hosted anywhere (so also on GitLab).
+
+The [utterances website](https://utteranc.es/) clearly explains the required steps. The given script can be added anywhere in your book, just copy the html-script into your `.md`-file or a markdown cell in your `.ipynb`-file. The blogpost is not visible when you do a local build of the book, build it online or use a local python server as shown in {ref}`setup-local-server`.
+
+Users need to have a GitHub-account to post a message. Although this might be a burden, it allows students to track their previous posts and set up notifications on follow-up posts.
+
+Below you see an example of this feature!
