How do I submit a URL that is too long into ...?

Sometimes you find that you need to save an extremely long link, like the one below, into a program that doesn’t allow links that long. For example Social Sciences Computing’s Classweb allows links to be 255 characters long, but the link below from UC-elinks is 384 characters long. 
 While waiting for the programmer to consider your request to allow longer links. 
 Another option is http://tinyurl.com . That free service converted the huge link below into a much shorter one.
