\label{Author_LON-CAPA_Introduction} LON-CAPA is a web-based interface that helps to organize and present your course website, deliver and manage problems, and manage student enrollment. All author functions are done through a web browser (Netscape 4.x or higher, a recent Mozilla, or IE 5+ required). There are two user manuals for LON-CAPA, a course coordinator manual and author manual. Also, quick reference guides are available for both manuals at http://help.loncapa.org. This is the author manual used to create resources such as problems that can later be added to your course. At this time, you should have: \begin{itemize} \item developed your objectives for your course. \item developed your problems for input into LON-CAPA and determined the appropriate question formats. Examples for question formats are provided when inserting a problem. \end{itemize}
