Would it be a good thing to put a little more VB code in to highlight the off-topic parts of a thread?

I know things have a way of digressing, and often a post is half reply to another poster, half reply to the original question or statement... I've seen (and used) stuff like this before:

[off-topic]
Insert off topic statement here.
[/off-topic]

It's probably impossible to eliminate off topic posts, but this might help seperate the conversations some. You could do it now with
Quote Originally Posted by Off-Topic

but then there's that 'Originally Posted by Off-Topic' thing at the beginning of each box... It would be cool if you could get it to just read 'Off Topic'.

I dunno, just seems like a good idea right now... Put a little box around the part of the post that doesn't have anything to do with the original post... And since the quote boxes do it, I don't see it taking that much effort...

Yeah.
