Welcome, Lisa and Darth!
The enTourage registration website is just down. It's a temporary problem (I hope!). Meanwhile, if you follow the directions Gunner posted in this link
https://www.mobileread.com/forums/sho...d.php?t=141898 you should be able to skip registration for now and get on with the important business of trying out your ne PEs!
You will be able to register later, once the website is back up.
Have fun!
P.S. Good one, fromage!
