The usage instructions are generic and don't discuss the specific options of the theme. Hasn't anyone ever used the Network theme so you've just left generic usage instructions?
The descriptions on the two most important fields in the advanced options page are cryptic at best. Exactly what is the difference between blog posts and network posts.
Exactly how does the "exclude these blogs" works? And what if I don't want to ignore any? Why is there always one blog selected? How do I UNSELECT all blogs so they are ALL included.
Does it only pull ONE item from each blog that's part of the multisite? If it does that's kind of an important piece of information.
All of that kind of should be in the usage instructions. . ... or something.
