Making the button was easy; getting the html to display as code (so that you can copy it) instead of translating the image, that was hard. I worked on it for several hours, and had some help in the WordPress.com Forum.
If you would like to add the Master’s Table button to your blog or website, copy the html code below into your blog template or a text widget. You will also find the new button and it’s coding at the bottom of the left hand sidebar. And hey, thanks for the linkage!
