okay so u want people to click your banner eh? well first of all instead of just throwing banners everyone how bout u make a table with banners and descriptions about the site like u can see on my site.. Also i see you have got the Purple lounge stuff that is a great poker room to promote because they give you free money! but there are alot more of those such as Royal vegas, Poker Time, Crazy Vegas and those are all from Fortune Affiliates.
Im not sure what your budget is for the league but i have done some things where i have offered my members a free t-shirt if they make a deposit using my link or saying that anyone who plays a buyin tournament will be entered into a special freeroll at the end of the month with a big prize pool mine was ($500)
thats about all i can think of right now hope it helped!
ps. just reread my post im not saying u just put up a bunch of banners everywhere. (sounded kind of harsh) srry.
