I often get emails that seem to be innocuous but that set off my virus warning. The reason could be innocent, or not. I have no way of knowing. In any case, please understand that I don't open such emails. So if you want to send me something, please eliminate imbedded images and fancy stuff beforehand.
If you have a straight up request, there is no need to adorn it. Likewise, although I often get e-cards and such, I NEVER open them. Caught a virus that way once. So, never again.
Insofar as request for reprint and forwarding, you have my permission as long as:
a. it is not posted on a racist or antisemitic site.
b. it is reprinted in its entirety, including the original date published.
c. it is fully credited with my name, email and blog address.
d. it is not used for fund-raising unless you have my separate, written permission.
