So you have contacted people with registration numbers < 10,000?

The answer to this question is yes. Maybe you should have rephrased it to say:

"So you have contacted ALL people with registration numbers < 10,000?"

Yeah yeah, I know I'm being picky! I'm sure the empeg guys really knew what you meant, but I'm interested in the answer too and didn't want to have it dodged by a witty response like mine .
