I have a client with an existing WordPress site asking for the ability to assign *personalized* files and calendar items to users. In other words, joe would log in and be able to see a list of files and calendar events that are just for joe, and mary would see a list of files and calendar events that are just for mary.
To me, this seems like a request that is stepping outside the reach of the capabilities of WordPress or any plugin I've ever seen, but wanted to ask the experts here before telling them this is a job for Django or another framework.
How would you go about solving this? Could you do it in WordPress?
