You may have noticed some new sections on the front page of the crew site. These are collaboration notification features which let you know when there’s new activity in one of your discussions. You can find out more about the new features here.
Discussions can be started by creating a post in a group that you subscribe to, or joined by adding a comment to an existing post. The comments form a threaded discussion and you can discuss anything of interest to the group, such as posting a link to an interesting article, suggesting a new idea or asking a question.
Groups can be accessed from the NETWORK option in the main menu (or directly at crew.isdc.network/groups). There are a growing number of groups covering different areas of interest.
Okay I'm loving the little red comment circles, and how they come up for posts I haven't even opened yet :)
