When you are logged in, your Account menu show 4 entries, discussed in this page after the image.
When you navigate to a page with a presentation, a button with a clock symbol is placed at the upper right corner of the video. When selected, the video you are watching is saved to your “watch later” list, accessible from the Account menu and at this link. You can use this feature to keep track of interesting contributions or videos you prefer to watch later.
Subscriptions allow you to receive a mail (from email@example.com) every time a new comment is posted to a presentation. You can activate a subscription using the “subscribe without commenting” link at the bottom of the pages containing a presentation.
The Manage subscription item in the Account menu allows you to manage your subscription, e.g. delete or suspend them.
If you are a corresponding author, you are already subscribed to your presentations and you should automatically receive an email every time a comment is posted to your video.
Do no hesitate to contact us in case of problems either using the form available from the Account menu or writing directly to firstname.lastname@example.org
