The @mention functionality allows you to link a person, place or piece of content in the community. When you @mention a person the user is sent a social interaction notification in their Inbox. Depending on their preferences they will also get an email notification. When you @mention a place it will be noted in the place’s activity stream.
Type @ to begin your reference
Whether you're posting a status update, asking a question, posting a comment or creating a document in the community, simply type the '@' symbol and begin your reference. A search dialog will opens and suggestions will be listed.
Use an underscore “_” as a space to search for names or titles with multiple words
For example, if you wanted to reference this guide, you would type @How_do_I to begin referencing the list of all content that start with "How do I..." Keep typing to narrow the choices further.
Select the correct match from the list
The new link shows up in your content.
