@Helen3 Thanks. I'm sure it's not a majorly problematic thing, but "I just scanned in the photo page of my passport" isn't necessarily that simple. I don't have a scanner, so it will require me to go to an internet cafe, pay to use one of their computers, call up the Airbnb site, navigate to the page in question, then get the internet cafe manager to to scan my passport so it is entered on the page. That's why I haven't bothered to do it yet 🙂
Of course, if I ever use Airbnb as a guest, it's something I'll have to do- I wouldn't want to keep getting declined becuse I had no verified ID.
