Comment Connection is a WordPress plugin that automatically links comments as authors reply to each other.
Comment Connection allows readers to follow conversations by automatically linking to comments that are replied to. This becomes especially important with longer conversations.
The @ symbol currently modifies comments, though more options may become available later.
In addition to the @ symbol, the reference must be followed by either a new line, colon or comma. This means that neither email addresses nor regular names are turned into a link unless it has the @ symbol.
Yes. Comment Connection will still find the reference if the case is different. Ex. @john smith: will reference the comment by John Smith.
