Google Adsens on a forum

Hi, i got a little problem:
I want to open a Call of duty MW2 forum but something to keep the site up should be nice..
So if i could place some google adsense on there that should be just.. great !
Well my question is: How can i put google adsense into a forum ?
EDIT: Oh btw, i would like having the ad under the header..
Yeshyesh, its a subdomain but i go buy an own domain its just to test everything so i dont lose a week or some getting the forum working..

What script are you using? It is very easy is you are running vbulletin... but adsense in forum is not good.. I mean low earning..

 

If its PHPBB3, i can tell you what to do easily as I have adsense running on one myself.

 

Have a look on google for some walk throughs. It is quite easy to do if you follow the instructions of where to paste the code.

 

@Shadowpope:
phpBB 3 it is
PM me please

Almost all forum software there has mods to manage your adsense's display on your forum.
