Titles like "Look at this" or "Is this for real?" can be ambiguous. "NCR" helps us decide whether to really look.

Personally, I prefer more descriptive subject lines, or at least a description in the body of the message. Too often a message is only a link to another website, which can be very dangerous to click. I have also occasionally railed against the generic subject line "ID Help Needed." It would be much easier to search those posts in the future if they described a chip: "ID Help Needed - initials JBC" or "ID Help Needed - jumping deer."

I have been guilty of posting NCR things without the NCR notation - especially my posts about postal rate increases. I hope that, even when I omit the NCR, my subject line will be descriptive enough. I will try to be more vigilant, though, because I also think "NCR" serves an important purpose.
