Can I have a blog to which more than one person posts?
Yes, these are called “team blogs.” Basically, one person initially creates the blog, then invites others to join it. Team members can either be administrators or regular posters. Administrators can edit all posts (not just their own), add and remove team members (and grant admin access), and modify blog settings. Non-admins can only post to the blog. To invite people to joing a blog, first go to the Settings | Permissions tab and click “Add Authors.” Next, type the email addresses of the people you’re inviting to the blog; they’ll receive an invitation email soon. Note that they must have Google Accounts, and if they don’t already, they’ll be prompted to create one. When you’re ready to send the invitations, click “Invite.” You’ll receive an email when the new team member has successfully joined the blog.
