I would want to know if I where the digitizer, so that I could correct the problem right away.
Funny you should ask. I think they would like to know. I was trying to download something and had to write to the owner because the link was dead. She was surprised and fixed it right away. A lot links get messed up and they don't always know.
If it were me - I would want to know - depending on how you approach the subjet - I can't see how they would mind.
