How to make my adsense banners only visible for guests?

Hello i want to add google adsense to my forum
I know already how to do this:

Display>Generalities
Homepage message
Message Content: (Put the code)

But i want to show the adsense banners only for guests
Anyone know how to do this? (My forum is phpBB2)
Thanks for the help

Hi,

Because your on PHPBB2, we can actually add the code to all pages, or do you rather to just the index page?

It will be though the templates at Admin panel >> Display > Templates.

I would like to see the banner on all pages, but only visible for guests. Can you please explain me step for step what i should do? Thanks in advance!

in the old forum you can change it from:

ADmin panel > general > configuration

for the new forum only administrator can not see them!

This is not answer my question, i need to know how to make my own adsense banners only visible to guests! And not the forumotion banners.. Please anyone a answer!

oh! sorry
you can put it in a forum description

and you can edit the permissions!

Sorry about the delay, I've had a bit of troubles with the templates, I'm out of touch with PHPBB2.

First, I need to let you know, that you have to remove the default ForuMotion adds by purchasing the removal Admin panel > Misc Spend credits (Or obtain, then spend) on adds removal.
It is only from then you can display your personal adds

Head to Admin panel >> Display > Templates / General > Overall_header, and in the first line, hit the [ENTER] button twice , and insert this code.
Remember to replace "Content" with the provided script!

Code:

<!-- BEGIN switch_user_logged_out --> <div id="pun-visit"> <p>{L_NOT_CONNECTED} {L_LOGIN_REGISTER}</p> </div> Content <!-- END switch_user_logged_out -->

Where exactly do i need to put this code with the Adsense script?

Just in the first line would be good that way it shows at the top of the forum, but anywhere really because it'll work anywhere you put it.
