User tags

[norv]

Purpose:
To attract the attention of a user, to a post/topic of their interest, in an easy to use and straightforward manner.
How it works:
Use @norv in the content of the post => Norv receives a notification that they have been tagged in a post, with a direct link to the post in question. The notifications page lists all their notifications.
Dealing with abuse:
Have at least: enable/disable notifications per forum (admin option), disabled more than n notifications made by an user per 15 minutes; enable/disable notifications per user (sub-option: per buddy list; disable from ignored users).

A few (very few of those existing) relevant discussions:
