Is there a @user plugin to talk about the user?

Question

I am looking for an add-on to talk to a user on a question, an answer, or a comment on a yada.
When we talk about it, there will also be a notification to her, is there a plug-in like this?

Answer 1

According to the legend, there was such a plugin. There were some complaints from people, though, regarding a couple of bugs. Maybe they had been fixed. Here is the post: http://www.question2answer.org/qa/31733

It seems the only link to the plugin is this one, as the author has removed the file from his Dropbox: https://github.com/ProThoughts/q2a-hashtagger
