University Portal

Hi, This is going to be basically a community site, but i need more specifications. For example, there will be a section called teachers and user should add their comment anonymously (if they want to)users should have a gallery on their profile and should link to videos(like youtube), there should be integrated to a forum (you can use forums in the scene now, but it has to have the same database) and also there should be a file database for students to upload their class notes, homeworks, etc. (this should be restricted to some users, i mean the uploader should choose the user willing to provide or other solution so that the teacher would not get it). There will be a little more specs but i will give details as long as the bid comes.
