I think someone needs to reply to all the comments before the predictions are closed. I say this because a comment with no reply can be edited by the owner. I believe you must have that covered already but if not, please make it happen. I can volunteer for the service each week for a small favor from you; may be upvotes on my replies.
EDIT:- I think it is my first #steemgig.
I usually do that, but I noticed that if you edit your comment it jumps up highest on my "reply" list. So I'm keeping a close eye on it and disqualifying users that do so.
