This is going to be my most important project

I'am looking for a social network just like http://www.bigadda.com/

I like how the tabs and the design is made, but the design im thinking of is in red and white

The tabs that i require are

video
photos
blog- the blog website should have the digg.com feature which allows you to connect to external websites.
forums
classifieds
polls
events
groups
news or articles
a store tab- this tab is going to be connected with users stores. I will tell later down.



The requirement for user profiles.

the user profile is the most important thing. in the profile user will be allow to socialize, and sell there own items, and every item they post will be put in the store tab.
User will be able to edit there profile by dragging items, they will also be able to edit there profile in a simple and easy way. User can also disable feature that they don't like .

The user profile should also include a virtual wall like big adda, the only difference is that very user is going to have a wall, and only friends could post on the wall.

I have many other feature I want to add, but I will add them in the future, I want to keep it simple and easy for users.

The social network should also include the twitter feature

I also want to get a relationship with the programmer I will choose to make it easy to add the other features.
