    Correct. I was referring to the banner type ads inside of posts when I am logged in. Those appear with any style type other than "vB Default".

    Another bit of information-

    Using iPhone Safari IOS 13 and changing "Style" to "Default vB" eliminates the ads in posts. They are there with any other style.

    fwiw:

    Using Firefox, Chrome, or Edge on Windows 10 I'm seeing none of that. With the exception of Chrome, I don't even see the top banner ad. Chrome shows a broken link in that space.

    I'm not familiar with Australian pipe and hose standards but in the US the ID of S&D couplings is slightly smaller than the OD of typical hose. That makes it possible to cut a spiral groove in the...

    Is it the math or the NEC that you think is a cock up? 2HP from 240V/8A would be a premium high efficiency motor. Are you sure the DCs were actually demanding 2HP?

    12A does sound a bit high, but let's redo your calculation:

    colors. c4 and c9 each have only two cells with 7. r4c4 and r4c9 can't both be 7 so either r9c4 or r7c9 must be a 7. thus neither r7c6 nor r9c7 can be 7 and so must be 1.
