Here is the list of steps which have been made to build up one lecture for the virtual course accessible via WWW.

First information was sent to several medical electronic conferences and also appears on the Web pages of the University of Pittsburgh. Then teacher prepared the lecture in Microsoft PowerPoint software including slides with pictures or/and text, comments and Web references. Then the lecture was sent by e-mail to Pittsburgh. The conversion from MS PowerPoint to html format was done and the lecture was put up to the WWW. Then a group of reviewers made a basic review, sent suggestions to the author and he/she made the corrections.
