Yeah, that's something that people who are used to fully threaded boards do a lot. It's extremely annoying. They write the WHOLE text of their message in the subject line (which might just me "me too" but they often write a whole long sentence) and then they end the subject line with (NT) or similar to mean that there's no body text. It's so common that a lot of people also use (more) in their subject line just so others will realize it's NOT a no-text message.
The entire practice drives me nuts. I *always* click on the NT posts anyway, just because I'm not used to it. And it seems to me like a subject line should just be a subject line. But if you're used to it, I think it's a time-saver or something. Bulletin board communications for very lazy typists. <img border="0" title="" alt="[Wink]" src="images/icons/wink.gif" />
