Mentions & Reactions

Mentions 
 
 @username notifies a person; @all and @here are powerful—use sparingly. 
 Mention a role (if enabled) to notify a group of people. 
 
 Reactions 
 
 Add emoji reactions to acknowledge or vote without new messages. 
 Filter for reacted messages via the room’s search filters. 
 
 Status & availability 
 
 Respect DND and away statuses; use threads instead of broad pings.
