Some organizations push content via email newsletters and other email content. PlacerSustain "pushes" very little content. Instead, the website allows for users to be selective about the information they receive. Users can do this by simply browsing what they are interested in, or they may subscribe to content by: subscribing to all content related to a particular post, or to all content published by a particular author. To do this you click on a particular post, and at the bottom of individual posts there are links to "subscribe to...." You may select the link for content about the specific post, or all content published by a particular author. Once subscribed, you will receive notification of content posting via email.
Here is a video on subscribing to content on the PlacerSustain site:
