The plugin for Wordpress 2.x will work in conjunction with WP-Group-Restriction_1.0 and WP-Publications-Archive_1.1 and will need to restrict access to files with the following rules.
Example: User is taking a course in basketweaving that adds class materials weekly. Each class will have multiple files that user is required to download and view. User may not have access to the file for the second class before he/she views/downloads the all material for the prior class.
It is my desire to have the functionality added to the existing plugns, therefor reducing development time. The author of these plugins have already granted license to add additional the functionality.
These two plugins already work together. One to archive files to a page, and one to restrict access based on the user group logged in to.
I envision the group-restriction plug to be extended to add users to the group with access as they download the previous weeks files.
Does this make sense? I'm willing to add additional information until this makes full sense to everyone bidding.
If you have a better idea as to how to make this happen, I'm willing to listen.
