Those popup ads on login are annoying at the best of times.

Now that another race is underway, they're driving me crazy! To do well in the race I need to login in to the game far more frequently that non-race days. Which means I see those popups so many more times! I'm REALLY over it!

Don't popup up a particular ad more than once a day.
By all means make the icons for them on the left pulse, or draw attention to themselves in some way, just don't make me click through them 10+ times a day!
