I tried twice to tag your book but the tags didn't take for some reason. There was a (2) beside each tag term. When I clicked each tag the number went to (3). But when I left the page and then came back to it I found the number had reverted back to (2). Don't know why that happened.
I think your tagging actually worked. If you use the back button on your browser it will look like the tags aren't there but they are. If you log out of amazon and back in, you'll see your tags.
I tagged your book as well (so they are all up to 4 tags)!
Feel free to tag my book as well!
