Community Portal - MySpace, Facebook, YouTube, Email, etc.

Hey Programmers, How are you doing? I am looking to setup a custom site for a specific group of users. While I would like to have the features of many popular sites such as YouTube, Facebook, etc. I would like to have everything programmed together so it's not like I am using seperate scripts for each section of the site. Here are the features I would like to have: Registration w/ Security Question, Email Verification, Forgot Password, etc. All Basic Features Invite - Users should be able to invite other users to the site through a simple invitation page. News Feed - I will provide the RSS for the news feed to be shown on the homepage of the site. Photos - Users will be able to upload to photo albums as created by admin in the admin section. Videos - I want this to be similar to youtube. Users should be able to upload, manage videos from site Events - Calendar of events Directory - Categories where users can post their own website/business. Title, Description, Photos, etc. Groups - Similar to the 'Groups' section found in most scripts, but with some modifications. EMAIL - I want users to be able to sign up for their own email address @mywebsitename.com. They will be able to send/receive/check email as you normally would. If anyone has a demo script with most of these features I would really like to check it out. Thanks, BCBC
