Allow commenters to mention other users in their comments
Enabling @ Mentions in the comment section allows others to mention people in their comments.
@ Mentions is in Beta: This feature has a lot of moving parts and it was decided to release the feature while it is still working out the finer details.
In addition, people who leave comments can opt-in to receiving notifications if someone has mentioned them in a comment.
Opt-in is Site-wide: When a user opts-in, they are sent an email to confirm their subscription. This enables comment mentions for the user site-wide.
