1) Lets say I have a domain[dot]com and I build on there. I have /admin and I created the video import and pic import for a video site. I dont have the understanding of how the member functionality be included within the code of the site (files with the code, lets say). I want my users to be able to upload videos, comment on other people's videos, add other people as friends and all these things really that a system like this could do. Can you explain to me how to set this up within the code?
2) Second question related to the first - How to solve the video uploading by users? Should I upload certain users videos to their folder or add them with the rest of the videos (like imported) in some way?
