How do I tag other people or Pages in a post?
To tag someone in your post, start typing their name and then select their profile from the dropdown menu that appears (make sure to capitalize the first letter of their name). To tag a Page, type the “@” symbol and then start typing the Page’s name.
When you comment on a post, you can link to someone in your response by following the same steps as above. Comment links create a link to that person's profile and may send them a notification so they can stay up-to-date on the conversation. Delete a comment to remove a comment link.
