I'm assuming you pasted the block diagram as an image in Word? Or perhaps you just drew it in Word using their autoshapes.
Either way is fine.
Drew it in word using their shapes. Thanks.
Early on, I tried several times over several days to submit my diagram which is in PDF format, but the upload didn't seem to be accepted. I tried today and it appears to have been accepted. Good thing it looks like I made it through phase 1 without it!
