Hi, I have added google adsense code using "Banners" plugin.

(They asked to "Copy and paste the AdSense code in between the <head></head> tags of your site") - How do i do that? Directly via head.tpl file?

Based on the demo, i created 3 boxes for banners.

1. Header Banner - 728 x 90px
2. In Grid - 728 x 90px (I don't how it will work)
3. Sidebar - 360 x 360 px

(What are the other best possible box positions to have google ads?)

Did i configured correctly?

If i predefine the size of banner boxes, google ads will work our banner box size?

I just see the empty space on header banner space, i don't see any google ads. (It requires approval by google adsense before showing ads on my site?)
