It would be a nice feature to mail a colleague a notification when he/she is mentioned somewhere while being offline. The user should be able to enable / disable this option.
Thanks for sharing this idea Tim! I'm keeping track of this wish and keep you up to date if there is any news.
A slack notification to that colleague would also be a nice feature
Would be a great feature so make it optional for users to receive email notification when they get mentioned. Not only when they are offline.
