I would like to have two advertisements in threads on my forum: one of them I would like to be a 468x60 banner and the other a 728x15 link unit. One of them will be placed after the first post in a thread, and the other will be displayed half-way through the thread (after the 10th post). Which should go where? Thanks in advance for any advice.
I've decided to place the banner below the first post and the link unit below the 5th and 10th post of a thread.
