The block on URLs is actually there to prevent prospective guests and hosts from just arranging an informal booking off site and cutting AirBNB out of the picture. It's the same reason you can't send phone numbers or email addresses in chat messages until after they pay.
So after we pay... it would be good if we could actually converse fully and share links.
The host also said that she had sent me a link to a web page with house rules that describes where recycling and garbage goes, etc. I never received this, and I presume she had just put the link in a message, hit send, and AirBNB removed the link and nothing else happened.
Once we pay, the conversation should be unrestricted.
