What is a Community Blog?
Community Blogs are shared blogs that multiple authors can post to. Everyone on the Web can read a Community Blog, unless individual members use the “Shared with Community” privacy option when posting. The privacy list for a Community Blog includes all of the Community’s members. Members must be logged in to read shared posts.
A Community blog is more or less exactly what it sounds like. It’s a blog set up for multiple people to post to. Generally it resides on one person’s Angelfire account, but they can invite users to post to their blog. Some good working examples are our Angelfire and Tripod Clubs (http://club.angelfire.com and http://club.tripod.com). These are working examples of our community blogs, where members help other members with Angelfire and Tripod related issues.
