I'd love to see a google adsense extension.

i.e. one that allows you to set a default figure for how often you want the adsense adverts to appear on your discussion page.

I have seen this type of thing in other forum software, where say after every 5 posts on a thread/page, is a google adsense ad.

thanks, wall! I will try this tonight.

Any time frame, even rough, as to when your extension will be completed?

Great stuff, wallphone.

Lost last night....so going to try your code today.

LOL!!

I tried it and screwed my comments up. Any help would be much appreciated...

@nuclearw
Google's scripts limit you to 3 units per page, so technically you could run your AdSense code within the comment loop (display an ad block after every comment) and only 3 units would display.

@nuclearw and joemad, I find both your code examples really hard to read (Wallphone isn't as lazy as me), if you pop some <code></code> tags around your code snippets and select the "Html" comment formatter (radio button just above the "Add you comments" button) then it makes it a lot easier to read. Thanks :)
