I can live with a loose posting order on big stuff as well giving everyone a chance to say something if they wish.  If someone doesn't have an idea for that particular scene just post as much here so everyone has an Idea of what is going on.  Otherwise I also agree with wolfs about the pets and such that are not even close yet.  or even jasper who is kinda stuck in limbo since he's not a fighting kind of guy but still very important to the story.  Mer I don't think you should have to wait either.  Perhaps at some point the main body of the group catches up with him if that's what you intend for him to do.  Maybe he gets to a point where he's moving slower than he would want and the group just kinda catches up of its own accord.
