WebMesh current i3 has to be equal to -I because it is the only current flowing through the current source. When you look at R4, however, the resistor current is the combination of (superposition of) two mesh currents, i3 and i2. You nearly got the expression for the voltage across R4 correct. It equals R4 (i2 - i3). dating site for rich
