Just activate the Thrillseeker Key in steam like you have done with the Early bird Key and you are ready to go when the 9th arrives 
sorry this may sound stupid of me, I have the second streamkey but where do I use that in steam, I click on thrillseeker in steamand it takes me to a purchase page!!!!!!!
any suggestions would be welcome, so looking forward to the 9th
You should have received an e-mail with instructions. Basically, it works as follows;
Early Bird owners have received a new Steam key for the Thrillseeker Edition which they can activate on Steam. The Steam key can be found in your Frontier Store account page.
Any idea when that email was sent Joel. I'm a real slacker when it comes to checking email and wondering if my spam filter killed it
Edit:
Disregard. I went to Frontier store page and found it under "My Key Purchases"
Thank you so much, done it and activated . I am so excited that less than a week we get so many goodiesThank you Joel
