Great, glad you got it sorted out.
In case anyone else comes across this in the future, here is the guide to setting up the slider in Forever:
Featuring posts in a slider on your home page is easy. You just need sticky posts with Featured Images. Every sticky post you have (up to 10) that has a Featured Image (at least 888 pixels wide) attached will show up there. Easy!
On the home page, posts with Featured Images assigned will display with the excerpt, whereas posts without Featured Images will display the full content. You can always shorten full-content posts using the More Tag.
