Restricting Edit/Delete to comments
I have a sheet where collaborators discuss open issues in comments column.
This is great as we can now have the entire discussion around one row-wise subject in its comment box.
But a problem is being faced, collaborators are able to edit/delete their previously submitted comments. And that disturbs the discussion. We don't want submitted comments be edited or deleted once submitted. Can this be done? Appreciate comments and guide tiips.
