But if you subscribe you dont have to be lucky to get a key (I was subscribed about 8,5 years but never got an invite from opt-in). It says "This is not a contest! If you are an AddOn author that hosts with us and you have been keeping your AddOns current, you are eligible for a key!"
I did not take a closer look at the new models yet but I hope the male models will be nice, too.
