Please post Arduino-related questions to the Arduino Forum or to StackExchange: Arduino. This saves splitting questions and answers between this forum and the Arduino ones.

Maybe if you put your electronics pages on a separate subdomain? Heh.

I was sort-of hoping that the big red letters in the message "Please post questions about electronics on the The Arduino Forum" would have some impact, but evidently not.

OK, I think I have it. I've added that same message to the page where you register to join the forum.

Problem is, it's too well-known now. Lots of sites link to my tutorials about SPI, power-saving, etc.
