I would do it this way...I'd load the first 5 (or 10, or however many have an acceptable load time), then on repeatEnd, I'd fetch some more and keep doing that as long as the repeater was generating repeatEnd events. So what should happen is that the user sees the first n posts immediately, then the scroll thumb gets smaller and smaller as additional posts are loaded. If your repeated component isn't ungodly heavy, this should be fairly efficient. HTH; Amy
