Thanks, guys. (and thanks for the comments on my photos... you can see why I am a little unsure that my work even fits the purposes of this magazine)
Having never published in a paid mag, I have no idea what "my rate" is, but I have a feeling that the "pay" is the fame and exposure they are offering.
I will sleep on this, but I'm starting to think that the answer is going to be no. I'm not desperate for exposure, and I doubt that their market and mine are two quite different audiences.

Thanks again.
