Within the AirBnB website (and phone app), it's currently almost impossible for guests and hosts to find out how to contact AirBnB. Most of the Help system pages devoted to such queries are either dead-ends or are "circular", pointing back at themselves. And the Resolution Center, which is one of the few access points for contact, isn't always applicable to the issue at hand. (For example, if a host's listing is broken in some way, or pricing/billing is behaving illogically).
Why can't AirBnB provide simple, obvious links on EVERY PAGE, that lead to information about how to contact AirBnB via email, telephone, live chat, Twitter, etc?
The coding effort to accomplish this would be next to nothing. Just DO IT, AirBnB.
