If you responded to EBT then your post would have been indented under EBT regardless of the time of the post.
That is the way Boardhost message boards work that being said you did type @EBT in your post so you didn't mean to post to mark Patterson.
So you are correct in that you wrote @EBT.
And I am correct in that you posted to Mark Patterson which is undeniable.
You must have read EBT's post then Marks post and responded to Mark thinking you were responding to EBT.
