Often, I receive emails asking me to open an attachment so that I can learn details about an event/fundraiser/etc. It seems to me that it would be just as easy for the sender to paste the details in the email body and save everyone the bother of having to open a document. It would also save our email servers from having to store documents that are not needed.
While I am at it, please consider not using PowerPoint to create a fancy-looking one-slide document. We need less "artistic" and more information, more simplification and less decoration.
And let me not forget this one: I will not support a fundraiser for a "health" cause that sells unhealthy products. Selling cookies, pies, and fried chicken to raise funds for the American Heart Association makes as much sense as selling guns to promote gun control, or selling joints in an anti-drug campaign.
