Whenever someone tags someone else in an article's discussion tab, notifying them to perform some action on a document, it would be useful to be able to see all mentions. This is a common approach for most software with the ability to communicate with other users. An email is sent when someone mentions, but if that email is lost or mistakenly marked as read, it may be missed. Having a place in the portal to show all mentions, would alleviate this issue and allow better management of documents.
