I noticed two clicks but I was making some changes and I don't know if that was me clicking on the ads. I've already sent an e-mail to to let them know that it may have been me. I am not 100% sure but I'm like 80% sure I didn't click and 20% sure it may have been me.
Two clicks isn't going to end the world (shouldn't be done and you've acted appropriately). But no, you hand over that space to Adsense and they know who clicked via IP tracking etc and they're unlikely to hand over their data to you - even though it was collected via your site. If you want control over the ads and the information then install something like phpAdsNew, source your own clients, handle your own billing. But that's alot of work...
Well but why at all do you need to know who clicked your ads.Just concentrate on how to get more clicks instead!!
