Okay, we are getting somewhere - yes there is Edit Category and I can see how to fiddle with these although a bit stumped on how to start a completely new category rather than a sub category.
Still can't see how to create new users. I can see user groups but how I do I set up the initial users?
The manual doesn't seem to tally up at all with what I'm seeing. Is there another one somewhere that relates to the current version of PhotoPost you are installing? If there's a thorough manual somewhere I could stop bothering you.
