Yes, I’ve read through it several times, and just do not see where it show how to add the URLs…
This is what I see:
Title – The title of your widget. (i.e. “I Love These Blogs!”)
Number of blogs to show – Enter the maximum number of blogs that you’d like to show here. We’ll try our best to only show blogs that have uploaded a Blavatar, or that have a user-image set. Blogs are listed in reverse order, so when you follow something new, it will appear at the top of the list.
Display as – You can show your list as either a simple text list, or as a grid of images. If you select Grid, then we’ll try to load a Blavatar or user-image for each blog.
