Best position for my Content ads?

Hello, Can someone here could please tell me where is the best spot for adding a content text ads from vibrant?

i only want to show the links inside the users/members post (not include Profile, header, footer, etc.) thank you..

I recommend you to check this thread at vb Adsense Within first post - vBulletin.org Forum and Best Adsense configuration within posts this topic. I personally apply 300x250 ads rock and made great difference for me. IT's vibrant and produce clicks.

I agree It's very clever idea to show only inside of first or "first and last" content of every topic.
