Hi Star,
Here are some answers to your questions;
Do you use a one-wallet system ?
Yes, a player at the sportsbook can play in the casino or racebook and vice versa.
Can you tell a bit more about marketing materials ?
We have a large array of banners in all different sizes, as well can create custom mailers, livefeed for your site as well as XML feed. We also have articles that affiliates can use and place on their sites.
Is there any way to get paid through Neteller for Non-US
affiliates (maybe player account) ?
We place the money in the players account for US based affiliates but can easily apply that to non US affiliates. We pay currently by check and bankwire, with plans to expand this in the near future.
We plan to make available to all affiliates XML feed and will consider RSS feed, however we would like to hear from affiliates what they would like to see in the RSS feed from us.
