I run a commercial wordpress site using a theme called "Emporium". A developer friend of mine set it up for me and although I update it regularly myself and change the pictures, prices, logos, text, banners and so on I am still a bit of a wordpress novice, to put it mildly. He has a young baby now and is pretty busy these days so I don't want to keep asking him questions when I want to later things.
So what I am looking for is a good guide book (manual) on WordPress. There are loads of books out there of course but there doesn't seem to be one that focusses on the commercial aspects / potential of WordPress - they all seem tend to concentrate on the blogging side, which is of course what wordpress is about, so that's fair enough! I have been around Amazon several times. There are 100's, so I may have missed some good ones..
Does anyone know of a book that might be a good bet for me?
I sell clothes on my site by the way.
