Morning all.
The new store is on the main operating system for the entire site now. If you are a forum member and are logged into the forum you will be automatically logged into the store and vise versa.
If you are a forum member and decide to place an order and are not logged into the forum you can use your forum credentials to login. If you are logged into the forum the store will just take you to the information page. If you are placing an order the store will only ask you to login to get more information like shipping information and such that it needs then you are good to go. Once it has what it needs, when you login anywhere you will be logged in everywhere.
The nice thing about this is you can see everything and go anywhere with 1 login. If you login to forum and decide to put something on the wishlist so you don't forget for later it will remember it without another login. Or if someone sees something they have a question about in the store they can jump to forum and ask.
If you have any further questions let me know.
