I'm sorry for such a delay in responding to your feedback request.
I have found it rather easy to change text on the web pages using your excellent instructions. I haven't had the opportunity to add pictures yet but that will be coming soon. I would recommend Joomla! for anyone maintaining a website themselves. Overall I like the way it works and the ease of using it. I hope this helps with your promotion.
