How do I notify users with a space in their username via comments?
I know that I can notify users that I wrote something regarding their comment by adding them by using @Username, for example "@Username That's a nice idea!".
How do I notify users who have a space in their name? Is it @UserName or @User Name? Can I add a characters right after @Username (for exmaple @Username, or @Username:) or will this break the notification?
