Hello, We need a program that must be invisible to the user. It will go to a specific site and find all outgoing links to other sites. It will then browse all external links one at a time and only one time If another program demands bandwith then it will stop If it is finisched with browsing all external links then it will unload and delete itself. In short this is it we are open for any ideas from you. Pls pm me with extra questions
