User Mentions
When you are typing in the post editor, type the @ symbol and (at least) 3 (or more) characters, which are matched against users' display names, and you are presented with a list of one or more users:
After you select the desired user, their DNN avatar and a link to their user profile are inserted into the post:
When you are mentioned in a post, you will receive a DNN notification:
There is also a user option where you can disable/enable these notifications:
User Mentions are currently powered by some custom plugins for the CKEditor4 HTML editor provided with DNN. We have a new editor option that allows you to select this editor instead of the default DNN editor.
This editor option is now the default for a new installation, and if you are upgrading, and it was previously set to Default DNN Editor, it will change to the new DNN CKEditor4 plus Forums plugins option.
In the control panel, there is now a feature setting that lets you select the "editor" for each forum, forum group, or default for the module (remember that you can have forums inherit from groups, and groups inherit from module defaults, so you might only need to set this for the module defaults and it will flow downward):
For new installations, this is enabled for Administrators and Registered Users. For upgrades, this will be set to match the security for "Edit".
You can then maintain the individual roles in the security matrix; this specifies which user roles can mention other users in a post:
