I want to develop a website that has family history information. Something like Ancestry.com but much simpler. I want to display photos, family tree, have logins and allow members to upload family photos,documents,stories and comments and have tags for the docs and photos and maybe a message board and blog.

Also, this is not for the general public but just my extended family. I'd like each person to have their own page with a bio, pics and information.

Is there anything that already does something like this? I don't want to waste time writing this if it already exists.

thank you

I'm familiar with asp.net and php.
