'''''Leafnode''''' is a store-and-forward [NNTP](/source/Network_News_Transfer_Protocol) (or [Usenet](/source/Usenet)) [proxy server](/source/proxy_server) designed for small sites with just a few active [newsgroup](/source/newsgroup)s, but very easy to set up and maintain, when compared to [INN](/source/InterNetNews).  Originally created by [Arnt Gulbrandsen](/source/Arnt_Gulbrandsen)<ref>{{cite web | url=https://leafnode.sourceforge.net/wuerzburg/faq.html#20 | work=Leafnode | last = Krasel | first = Cornelius |  accessdate=2006-08-15 | title=Leafnode FAQ}}</ref> in 1995 while he was working at [Trolltech](/source/Trolltech), it is currently maintained by Matthias Andree and Ralf Wildenhues.

The term '''leaf node''' can also be used to describe a node on a [binary tree](/source/binary_tree) (or any other sort of tree that has nodes) which has no sub-nodes.
