Web App using Google API's to work with Google Groups

I have a website with users accounts, the users are also members of a Google Groups that I manually manage. I know that Google allows for access in to Google Groups with their own API's. I have setup my Google Groups account for access with API's. I have already downloaded and played with the Google API library in PHP from this link: [login to view URL] I have successfully gotten the PHP page to access my "test" group and list the members of the group so I know it's working. But now I need a project (a new PHP page) done to do the following: 1. List all the members of a specific group, showing only their email address. 2. Be able to update a members email address of specific group or all groups, in other words replace an existing email address with a new email address. 3. Delete a specific member using their email address from a specific group or all groups. This project will be PHP pages that I can use on my own website. You will create the PHP pages to do the things that I listed above. The PHP pages code must be able to use my own Google ID. Here is a link to the Google API for Groups: [login to view URL]
