Putting ad spot beween say 20th and 21st posts in thread?
 

I searched around and didn't find a current way to do this to the templates (partly because 'ad' is only two letters), so forgive me if I missed it, but what I am looking for is a way to insert an ad banner spot between say the 20th and 21st posts in a thread, for all threads. Something like if thread has 25+ posts showing on this page, put an ad spot between number 20 and 21, or whatever.

Can anyone point me in the right direction? I looked at some of the ad management plugins/mods and the current ones don't seem to have ads between specified posts as an option.

I would like to know this too.

I think the variable you would look at is $post['postcount']. So at the top of your postbit (or postbit_legacy) template, you would put something like:

Is there a way to count posts as a multiple of a number? Such as multiples of 10, ie. 10, 20, 30, 40... So the conditional would only apply if the post count is a multiple of 10...?

What you do is something like ...

That may not be exact... look up php operators. You want to see what the remainder is after dividing by 10 - I think it's called the modulus or something like that. So, if 10/10 has a remainder of 0, then you do something.
