On some other systems, once you are “mentioned” you are automatically watching that topic.
I think this would be useful for communities who are used to such behavior, and/or where login is required and the members already have a high level of trust with each other.
Here’s my proposal for this feature:
When someone quotes me, mentions my @username, or invites me to a topic, set that topic to [ Watched | Tracked | Normal ] default is Normal.
The specific proposal above is based on the verbiage in the existing user preference (below) and the proposed spec for this other feature request here: Automatically set Topics to Watching after posting
