Need ideas on starting a family website or something

So the Taggards are now spread all over the place and no one seems to know what is going on with the other families. Amber and I were talking about setting up a webpage or something where everyone can post whats going on, share calendars, pictures and stuff like that. I know some of you have sites like that for your families and would like to know how do you start it and all that jazz. Any help would be great.
