Timely that this forum discussion was created as we were in the process of adding new functionality to the Forums.
We’ve fixed the inconsistent tagging bug, and updated the logic for @-Mentions. Recent Commenters are weighted in the initial suggestions, with users filtered as you type their handle. We’ve also included avatars, if present, to make it a bit easier. Below is a screensht of what that looks like.
As some users mentioned, there is a difference in the the notifications you can receive. When you get mentioned, you will receive an in-app notification (bell icon at top-right). The checkbox in your Notification Settings controls whether or not you also get an email.
In addition to the mentions fix, we’ve also rolled out new functionality on the Forums. For full details, visit the Forum Updates 11/12/2021 discussion.
