Before you leap to your keyboard, please take note as to what the Blog's special terms and conditions are (which you have accepted):

As chief editor of Your GandiBlog, and owner of the domain name associated with Your GandiBlog, You are held fully liable for the content published on Your GandiBlog, which notably includes, but is not limited to, all information data, text, software, music, sound, image, photograph, logo, drawing, video, goods, product, service, signs, signals, writing or messages of any or all nature (hereafter referred to as "Content") that is published, transmitted, or made available to the public via Your GandiBlog, including in the event of a Licence of Use, whether or not You are the author or responsible for its being made available online.

How does this work? It is quite simple. Click on "Writers" in the "System" menu (the left-hand vertical menu in your blog's administration interface). Next, to add a Gandi contact, enter his or her Gandi handle (in upper-case letters) and then select what rights you want to allow them to have in administering your blog. It is not possible to transfer full administrative control of your blog to your "mandated user" as that could lead to their possible deletion of your blog (which would be bad...)

To delete a "mandated user", simply uncheck all the permissions that you gave them. We will continue with the rest via the forum, which will soon be online.
