Um, I have no idea where to post this thread, but this one seems right, so anyways, On my forums, i want only guests to view my Ads, not registered users, My forum is Powered by Vbulletin, and I aint using any Plugins for it, I edited my theme's template and put the ad there. What code Php/html should i put there to prevent my users seeing it, and will it effect my adsense, cause editing the code is wrong ? :S
Won't affect your Adsense as you are not modifying the code from Google only changing when it is deployed - something that is even done on this forum. I doubt you asked this in the right forum and might want to ask the mods to move it to one of the programming or scripting areas.
