As an amateur without much Joomla! experience, or even website experience, i approached this with some trepidation. However, I found the interface excellent, with the same look and feel to it as Joomla! has. I liked the Help feature greatly, in that it integrates so well into the browser page.
My only initial setback was that I didn't realise at first that I'd need to set up the mail server. Once I understood that, it was all plain sailing. Well done.
