I am using Joomla 1.5, have bought DocMan and Community ACL.
My project will have 100 members and 400 "cases", each case will have 2 members (occasionally 3 or 4) and each member will be involved in about 8 cases.
The member will post a document/file to the site, and the only persons who will be able to see the document/file will be the poster and the other member of that case (administrator also).
I want the member to be able to log in and have his or her "cases" appear. The member should be able to click on the case, and see what has been uploaded, download any of the uploaded documents/files, and upload a document/file. No member to a case will be allowed to delete a document or file.
