How can you come up with 3 urls for banners4bucks?

Tweet

I am two shy and am trying to figure out how to get that straightened out. They state they will not pay the monthly payment until I have three links. I'm a memeber of many sites, so if you know on that has three urls to it where I can post the banners, please let me know. Apparently, three different sites are not considered acceptable, they have to be the same site. I'm left scratching my head, because I have no idea where to find this. I gave them my myspace ones, but I just have the homepage and blog urls to send them. They haven't even approved the blog one yet, so is there another url I can give them from myspace or is another sites urls better? Thanks for any advice!
