Gee, thanks for setting the bar a little higher, boccaccio. I can't come up with one title, and now you want seven?
I do know what you're talking about, though. When I search my e-mail archives for a reference, it's a lot easier to find what I'm looking for if each e-mail has a unique subject header. When I go back over my (let us say) Alex Bragi archive, all I see are a sea of "Hi" and "re: Hi" headers, and I'm totally lost.
("Hi" Alex!)
