Click or view one of your posts/submissions. Then find the View Source link of your browser and click it. In Internet Explorer 7, for example, it's Page > View Source. Look for the AdSense script and you'll see your Google AdSense ID. If not, and you see WriteLit.com's ID, refresh/reload your submission/post then View Source again. If you see your ID this time, then it's, of course, working. Your ID is used every other reload or viewing of your submission/post.

If you have any other questions just post a comment below this editorial. :)
