Does this feature actually work? I've been trying for several hours to insert some static html between the first and second posts of a topic and can't get it to work. I'm selecting the custom island insert under the forum settings on the control panel, and nothing is happening. I know the code in the custom island works, as I use it elsewhere. Any tips? Is there anyone else that has gotten this feature to work?

7.3.1 ?

In 7.3.x you need to set the forum permissions to force your groups to view the ad islands.

We use all 10 of the custom islands for a banner ad between the 1st and 2nd post and when I upgraded from v7.1 to v7.3 this option was not set (to force viewing).

yep, it was permissions. thanks for the quick response, guys!
