>I think I know what has happened with my post.

'brick and I exchanged some thoughts on this problem of responding to posts after some passage of time and having said response end up at the end of the thread. like you say, the threaded mode can help a bit; but overall it leaves a lot to be desired too. we finally agreed that the least bad alternative is to quote a bit of the post to which you're responding, to give your post some context.

hope this helps...
