Im just fooling around with adsense to start and im putting it on my forum site. How would i go about doing this? Will i need to go into Cpanel or what? Im very new to this.
Not cpanel no, you edit you website and place the adsense script on your pages - If you have a wordpress blog you can use an adsense plugin which makes it much easier. Note you will still have to login to adsense itself and setup the ads (size, type, etc).
go to your forums control penal (Not to your hosting panel) , and find the place where you can set your adsense code. or simply search for some plugins that are created for forums..
