Hi I'm really struggling to get started with EasyEDA. I have a very basic amplifier circuit with a single transistor and have drawn the schematic but when I check it to go forward to the PCB design it comes up with NET errors saying the circuit must have more than 2 pins?   I was under the impression that I didn't need to configure pins as I wasn't using a chip.?   Capacitor C1-2 seems to be throwing an error.  I also have 2 wires going to a potentiometer to the right of the schematic which isn't showing as I don't want to mount the potentiometer on the board.  How do I deal with this?  Thanks!
