The app is intended for people who live or work near you - people you see in your day-to-day life. So present yourself the way you really are. That’s not only vital for cultivating a respectful atmosphere within the community, but also lays the basis for trusting interactions between you and the people around you.
Another important reason for using your real name is to facilitate communications between you and your property manager or your onsite manager. All of your Service Point / Help Desk requests will also be sent under your real name so that the recipient knows precisely who sent them.
