Thank you Jenny. Good to know. It's strange that this domain is not listed as a "safe domain", and also the fact there doesn't seem to be a way (an easy one, at least) to find these messages from my normal environment within AirBnb.com! Still, thanks for clarifying!
Thank you Mike (or Jane? 🙂 ) ... I can see them here indeed... but I'd hoped to be able to access this from my "normal" hosting page, within AirBnb.com. Anyway, now I know! thanks again
