@Karen1214,
This is a discussion forum with mostly hosts as participants. You should submit your request by clicking the Help Center link at the bottom of your Airbnb page. Just a head's up, they are severely under-staffed, and you probably will not get a response for a human.
In the meanwhile, I suggest that you paste and edit your content in a blank document page (for Windows - Word, Word Pad, or Note Pad), and then copy and paste the revised content into the small message window.
