What can I use to build my own social network website?

I recently attended a once-in-a-lifetime family reunion, meeting family I never knew existed, along with those I knew fairly well. At the event, I took the opportunity to shoot each family member introducing themselves on video. Shortly thereafter, the idea arose of creating a MySpace clone just for our family. We could put our pictures from the reunion, as well as our own pictures, and the video introduction could be on each member's page, etc.

I am wondering how to go about doing this. Is there a website kit I can find somewhere? I've been browsing some sites, came across Dolphin - but that appears to be a dating site by the search fields I saw, and Mashable was interesting but didn't seem to have any articles that could help me.

Can anyone suggest any software or something similar that I can use to set up such a network?

Thank you!

You can go to sourceforge.net and see if they have a script that you can use and you can find scripts to purchase, some free at hotscripts.com that will do what you're wanting. You'll have to read instructions carefull and do the uploading andediting of the program onto your website host yourself.
You can search for some open source programs.

Also, you could learn PHP, and write a website.

Then use a free host like 4000webs (no, I'm NOT trying to advertise here) or 110mb.

Or you could ask someone on a forum or IRC to write one for you.

I'm not sure if there is any in the Web, but the better thing to do is to create it using PHP
A blog like word press is a good starting point. You can add video clips and audio clips and what's more family can opt in to posting to it. WP is a free download. Getting hosting is also very inexpensive. You probably already have the ability from you IsP.

Yahoo groups is another way to do it, just create a family group and off you go.

There are also many php scripts available for member sites it just depends on how involved you want to get.
