2 scenario's:
1. mentioning the reporter does not send a notification
- person which needs to be mentioned is the reporter
- has site acces
- is not part of JSM project - no permissions
- can find the person's name when tagging
2. can not find the person in the list of suggestions when tagging
- has site access
- is not part of JSM project - no permissions
- can not find the person's name when tagging
Does the users you want to mention have project permissions?
In what situations is @ mention used? And what are actually the conditions?
