I can't find a person in the community

There can be several reasons explaining why you cannot find a person in the community.

1. You are not connected to the Internet. Check that you are connected to a WiFi network (or that cellular data is activated for Andaman7).
2. The person you are looking for doesn't have an Andaman7 account yet. You can invite them to join the Andaman7 community by clicking on one of the sharing buttons on that screen.
3. The person changed her settings to hide her profile in the community search results. To check that, she should go in the menu more > My personal information and check that the setting "Hide your profile in directory" in the users directory subsection is not switched on.
