By default each stack has a chat channel that allows viewers (and the author) to post questions, comments and answers that attach to the stack. The chat channel is a single discussion thread.
You can choose to get email notifications of new chat activity on your ePoster. You can turn this on in the ePoster editor. The email notifications will be sent to the email address that you used when signing in.
It is also possible to turn on the email notifications when you are viewing any ePoster. You just open the chat area of that ePoster and then turn on the email notifications. You can do this for your own ePosters and for other authors’ ePosters. The email notifications will be sent to the email address that you used when signing in.
For more information on how delegates and authors can engage with the published showcase ePosters, you can view the Showcase Help Page.
