It seems like you know quite a bit about content management in OpenACS. I am trying to write a paper to evaluate all the different packages that deal with content management on OpenACS. So far I know about CMS, Content Repository and ETP (how do they all work?). I need to find out what are all the packages that deal with content management, as well as their various functionalities. Any lead or information that you have. I am also trying to find out about to use them on my current instance of OpenACS. I tried using the CMS but I always get error messages. Thank you for help.
