User story: Receive e-mail updates on new content by topic

(During our LOTE3 event at unMonastery Matera, we collected user stories for improving the website. This is one. You can find all of them under tag “project-userstories”.)

Story: “A user finds some interesting content on the website by using the site search function and tags (or hashtags). After that, the user can subscribe to get updates on new content that matches this search in the future. The same functionality is available after creating own content and tagging it with some tags or hashtags: one can then subscribe to receive updates on “similar content” in the future.”
