Hi Paukz, I'm not sure if adsense will accept your site due to lack of content. However, if you are already accepted, I would put 250 x 250 ad units near on your proxy page. It's worth a shot, you can always remove it if you're not earning any income from it.
That was fast. Just the proxy site (which is 3 pages total?) or another site? Let us know if you get in (I'm curious because they rejected my small site that I had a few years ago).
Hm...what are the results? I applied for adsense with my blog which at that time only had 1 post, and I got accepted anyway!
