I think the question is, are there any wyndham points owners using the crossover points grid to exchange through II with their Wyndham points? Wyndham has made a big push to get the grandfathered eligible Wyndham points members to change over to RCI (losing their grandfathered status) over the last 5+ years.
Since the question has been asked twice in the last two weeks and no one has responded affirmatively, it doesn't seem likely that any active TUG members fit the bill.
