TNT is an open source instant messaging client which is designed to use AIM and uses the AOL TOC protocol. The client is run within Emacs or XEmacs and is written in Emacs Lisp.
The client was originally written for AOL, but the project was abandoned around 1999, along with its other TOC clients, TiK and TAC. Since then, independent developers have continued to add features and make new releases.
TNT has been revised to work with the TOC2 protocol.
