Have rolled a mentions system to all Create A Forum forums
Works by using @ followed by their membername/displayname
For instance
@forum is now tied to member name.
Also under Profile -> Mentions will list any members that mentioned you along with date/time.
Notes:
In order for members to use this feature you must give them the "Mention members" permissions under their membergroup in Admin -> Permissions Found in the "Use basic forum functionality" permission.
Also you can't mention your self
By default the person being mentioned will be notified via email. You can disable that under profile -> Metnions
Enjoy,
Create A Forum
