I want to give a supplier access to one of my secondary blogs but not the main blog. Is there some way to create a separate userid and pw for that secondary blog? This is a volunteer who wants to help organize access to data from my blog for followers. I can put material on one of my secondary blogs for him to work without Admin access to the primary blog.
