When you register, you are asked to provide a profile picture in order to finalize your account.
Why a profile picture?
Unlike many other platforms, GEEV is focused on human exchange.
A picture shows other Geevers that you're genuine, reliable and want to be part of the GEEV community. You'll have a higher chance of giving and receiving objects, if you provide one!
However, you are free to put the profile picture you want.
