Aaargh! HTML mail with gratuitous images! The horror!
That's been my standpoint since HTML mail first came out, but I'm beginning to wonder how tenable it is. HTML is still an issue for email, and certainly I'd hate to see us send out messages only in HTML, but in some cases it makes sense. Is this one of them? Maybe. The typical Friend is probably used to it, and getting a message only in monospace text would probably appear unprofessional. I can see my stance softening, anyway.
