Thanks. My next question was how to migrate the proto from thru hole
to SMT. Also, there dosn't appear to be a TO92 package in the version
of PCB that I have.
BTW, what's wrong with labeling the pins EBC in both gschem & pcb?

I believe the TO92 is EBC (123) and the SOT23 is BEC (123). What I do in gschem is have symbols called BJT-NPN-EBC.sym and BJT-NPN-BCE.sym. You still need to verify that the footprint matches the schematic symbol. If you like "heavy" symbols you could create a 2N3906-TO92.sym or a 2N3906-SOT23.sym that has a footprint attribute and the corresponding pinout. (* jcl *)
