hi,jdev！
      I am a college student knowing just the basic c language.I am interested in  Jabber and now learn the the sources of server Jabberd2.0s6. I  want to do some work about it , knowing what a project/appication be like, how to program it.But i don't know how to start it facing these codes. 
     I have known the basic idear of Jabber and the associated knowledge such as DNS RSV,dialback.there is lack of  preject experience or advance C programming? 
     
      Could you please give some advice about how to learn the source of a project ,especially  Jabberd2.0s6?
