after reading the above thread....
currenty i'm renting out my basement to someone.
that is sending money order from the US.
they will sent first month/ last month plus air ticket fee.
they ask me to cash it first, then ask me to sent the air ticket money via wester union to her in africa......because her dad work in africa.
this is a fraud right?
how do i protect myself?
