Aaron, there are times when simple mentions do add to the conversation. Typically they include the text of the mention but the meta data hides them because of the way things are set to display. In those cases I often go into my database and manually change them to replies so they display the way I want them to. I’ll try to document the procedure so others can do the same, but there has been talk of adding code to make it easier to change directly within the amin interface. I don’t think it was a huge priority at the moment though.
