John, I wouldn't worry to much. All are veterans of the forum and will do the right thing one way or another IMO. Jerry could make a new account and post the review that way, but AFAIK that is against forum rules as having multiple accounts or creation of a new one due to a ban. He could do the review, and you could post it as suggested. I don't think anyone believes you would change it to benefit yourself. You would just need Jerry's permission to repost his review information considering the present situation.
What I read, Dave just took a step back for a bit as a moderator. He can still post, review and fulfill his commitment if he chooses to do so.
If either decide not to review, for what ever reason, I truly believe they would pass the unit on to the next in line by the pole results or return it to you to do so.
It is an unfortunate situation for you, one I believe is temporary, but I feel you will get what was agreed to in one manner or another.
