A way of organizing and displaying the sequence of articles that make up a conversation. The News protocol and many news readers have built-in support for this mode of operation. WinVN has direct support for threading if you have the "Compute Threads" option enabled from Config Article-List. You can also use "poor man's threading" by moving to the next article on the same subject with the "Find Next Article Same Subject" menu command. There is also a hypertext support of accessing news reference headers. You can click the mouse on a news reference header and WinVN will fetch that article and display it for you.
