title: Software for Sequence Diagrams?
body: <p>I've been using <a href="http://nclass.sourceforge.net/" rel="noreferrer">NClass</a> for object/class modeling in class thus far.</p>
  
  <p>However, I do not believe that it is capable of sequence diagrams, which is my next task.</p>
  
  <p>I would prefer not to use Visio. Is there a good and free software solution for making sequence diagrams? </p>
