Thank you. The DWG and the "0-hour block" would be a possibility (which I didn't know about yet); but these mistaggings I criticised are not so serious that I want to bother the DWG about them or revert his changesets. What I criticised can always be easily corrected later if he continues with that. I have now corrected the things I criticised so far myself and perhaps he will see that by chance at some point.
