Re: Don't reprint header

Well, how can you tell if you told someone something?

You can remember whether you told them or not.
You can ask them if you told them or not.
You can observe for the effects of having told them.

There's no way to do the last two, so that leaves the first. You need to keep track of it. (If you're using some library or framework, it may track it for you.)

It's a bad design to output all over the place. Your problem is the consequence of using that design.

Update: Fleshed out my reply.

The fourth way, as you suggest at the very end, is to: Have a policy of not telling people anything until just before you go home for the day. Not so good in social situations, but it works great for web pages.	[reply]

Not really, it just shifts the question from being about the message to being about the day. And these shifts are quite common in social situations. (I'll publish my report at the meeting. I'll discuss my plans after I nail down some details.) What I suggest at the end is really a means of tracking it. (Code X never tells, so I know that code X didn't tell.)	[reply]
