Both the forum name and the the (hopefully descriptive) topic title is displayed on both the index pages and probably less noticeably on the individual message pages. Do you ever look at those things?
I don't see having the message 1 content more available as having much effect on topic theme awareness.
Just looking at the message you're about to reply to probably could supply strong hint about the on or off-topic state. Is there a scatter-shot of themes in the message? Probably most and maybe all of those themes are off-topic.

ps: Your topic title sucks.
Is/was "Software suggestion"
