Although we don't have any current plans to allow review responses to be edited, I have registered it as a feature improvement request.
If there is any update on this at all then I will let you know.
This needs to be adjusted ASAP as we seeing reviews from people already which are one sided and not entirely true and this can effect the viability of our business considering we pushing all our booing customers through ResDiary!.
Can you get confirmation whether this is going to happen or not?
Would we be able to have a function to edit a response submitted for a restaurant review on the site?
