I am trying to develop an web page/appplication where users and visitors of my site (running on OpenACS 4.6.3) will be able to upload and download files. These files will be sorted and indexed according to different categories. I want to develop a site with functionalities and user abilities such as the one for photo.net. Which package(s) should I use for that? I thought about the content-repository package and/or the content management system. Which one should I use? How do I use it to create/and content, search them, etc.....
Thank you
