You have to be patient. Microsoft may even be going through their list of who reserved first and you may have been later in the line...
I am going to "reserve" a copy at around 7 am Central time, I will let everyone know of any progress. If it isn't being seen in the Sticky. But I assume it will start to download and after that download is finished and the appointed time is achieve, you will get a notification it is ready to install.
Edit: Maybe we should be asking if folks are signed in with a Microsoft Account.....
