THIS IS A CRITICAL THING TO DO BEFORE MOVING TO GOOGLE APPS FOR EDUCATION. IF YOU HAVE BEEN LOGGING IN TO BLOGGER WITH A email@example.com ACCOUNT YOU MUST SHARE THE LOG IN IN THIS WAY WITH AN EMAIL ADDRESS FROM OUTSIDE THE DOMAIN.
If they move in to Google Apps without changing the log in they will still be able to write their blog but will not be able to moderate comments, have admin access or change their themes or add to their side bar! All important things to be able to do.
There are two levels of permissions.......
Just being an author lets you write posts but not change any of the other settings or add links to the side bar or anything. This would be the level you would want to give to child authors or co-contributors.
The second level of permissions is that of administrator. This is the level of permissions you would need to hand on to the new teacher so they can add links and customise the blog for the new class.
To do it the administrator of the blog logs in and goes to OVERVIEW then SETTINGS.
Add an author.
The recipient will get an email asking them to join. They will need to make a Google account to be able to post. With Google Apps in school that will be nice and simple.
Once they have done that their email will show up in your list of blog authors.
At the moment the new person can only add posts. Good for child access.
For the new teacher to successfully administer the blog and add links to it and customise it with new widgets and the like they need to be granted administrator privileges.
To change an author to an administrator click on the drop down menu to change it.
If the original creator of the blog no longer wishes to be able to administer the blog they can now revoke their own privileges but it does no harm to have two administrators. A nice back up person if somethings goes amiss.
