Above, there is a box with some advertisement, when you click it it takes you to a different page. How do you get your advertisement to be up there?

@ You have to buy one of these [item=Billboard (10k)][item=Billboard (50k)][item=Billboard (100k)] ..from the Cash Shop or from other users.

Then you make your own ad and submit it for approval. When it's approved by the staff, it appears up there ;)
