Would you like to insert an advertisment panel between forum posts for higher revenue?
Then paste the code below in an horizontal panel.
Go to your "Admin Panel" --> System Admin --> Panels
Create a new "Upper Center" panel.
Give the panel a name, for example "Ad"
Keep panel filename the default value "None"
Remove all panel content and replace with the code below.
Panel restriction should be "include in these pages" and leave the field blank.
Panel access should be public.
Check the checkbox for "Display panel on all pages".
Save the panel and enable it.
Before adding your own ad code to it just try it and check if you see this sentence; "If you can read this your code works". The code <!--forum_thread_prepost_2--> (2 times) determines where the ad is shown. In this example it is shown directly under the first post, so it is the number 2 post.
If it works, and it should, remove "If you can read this your code works" and add your own code.
