It's great to see you engaging with the community center! The reason I have removed your phone numbers is because posting personal information is against our Community Center Guidelines .

There has to be away for the community to exchange contacts. It should be on a closed forum, So that hackers can't get it (like they do from HOMEAWAY) and Airbnb should not lose business.
