When I "arrived" here the other day I followed the convention of starting a comment with a @ and the name of the person I am replying to etc., but lately this has not shown up on my comment. If I go back in and edit it in, the system edits it out again. Am I doing something wrong or is this the "technology just not working" again?
@name is automatically removed where
- you are addressing the post author and
- there are no ambiguities
Authors automatically receive inbox notifications of all comments on their posts, so if a comment is addressed to them, it doesn't need the @name address. If there are other commenters on a post, and you need to differentiate between a reply to them and the OP, then @name should be retained if even that is the OP.
@name is retained when you are replying to a commenter who is not the post author.
It's been part of SE functionality since July 2011.
If you found @name being removed under other circumstances, please edit your question to give full details (including a link to the comment, which you can get from its timestamp). If that's the case, the bug tag can probably be reinstated.
