I assume that you are new to this forum, you can check your earnings only by looking at you user CP and go to banking and donation section to see your current credits. 1 credit equal to 1 cent, and all sections there is paid section, of course when you make posts your credits will be increase. The maximum you can get for 1 post is 5.1 cents.
There is no "banking and loans" tab anymore. It has been changed to "earnings" long ago. The activity of the forum is increasing fast but still I'm not able to make much posts and so far I have only 25 posts.
