ArgMAP is a MS windows computer program for drawing argument maps. It was written by Joe Lau at the University of Hong Kong. It is free for non-commercial use, but this program is no longer under development and its functionality is limited. The last version of ArgMAP is v0.9.1, which you can download from this page. The program was still in beta so save your work frequently and expect mysterious crashes now and then! No warranty is implied.
