I currently have a blog and would like to add a second blog. I’d like to add editors to the second blog because it is going to be a collaboration. I just want to make sure that if I add editors to the second blog via the invite users tab that they will not have access to my original blog.
The only access each user has is to blogs to which they have been added in some capacity. (See FAQ What are the different roles? for more info.) So if they are not users on your original blog, they will not have access to it.
