See my post above. It's easy to check your limits. Just enter in numbers while logged out and then do it while logged in. If it's the same you're not limited at all. Otherwise, you may be at some % (I'm 10%). But, how much do you want to bet? For example, their NFL spread limits are > 30k. Most major markets you'll get 10k.
Congrats of course, but mid five figures is nothing.
I always type in a bunch of 99999s to see my limit so I know how much to bet.
