I have been looking at the French forums to see if there's a clue as to whether there will be an extra gift if you open all the windows.  Here's the link for that thread/announcement:http://www.ohmydollz.com/forum/viewtopic.php?id=91114

(used google translator)

Basically it says:
Coucou les filles !

C'est sous ma couverture que je vous écris cette news ! Il fait sacrément froid dans ma maison mais je vais aller me réchauffer avec une bonne séance de squash ! aomd_smile

Demain c’est déjà le premier décembre ! La période des fêtes commence et avec elle, son lot de cadeaux ! Nous ne sommes pas chocolatiers sur OhMyDollz (bien que gourmands) mais nous aimons les surprises… Alors nous vous avons préparé un beau calendrier de l’avent tout plein de jolis cadeaux !

Ouvrez chaque jour une case de votre calendrier OhMyDollz pour recevoir un joli cadeau dans l’esprit de Noël !

tranlation:

Hello girls!

It was under my blanket that I write this post! It is damn cold in my house but I'll go warm up with a good session of squash! aomd_smile

Tomorrow is already December 1st! The holiday season begins and with it, a lot of gifts! We are not chocolate on Ohmydollz (although greedy) but we love surprises ... So we have prepared a beautiful advent calendar full of pretty gifts!

Open every day box Ohmydollz your calendar to receive a nice gift in the Christmas spirit!

Si jamais vous manquez un ou plusieurs jours, il vous sera possible d’ouvrir les cases des jours précédents en échange de 15 fee’z la case !

Vous l’aurez compris, faites en sorte de rester connectées !

Bon weekend les filles !

translation:
If you ever miss one or more days, you will be able to open the boxes of the previous days in exchange for 15 fee'z box!

You will understand, make sure you stay connected!

Good weekend girls!


So that thread doesn't mention a BIG gift if we opened all of the windows, so I'm going to throw out a guess here that we probably won't get one.  And part of the reason why we are not is that last year there was a huge thing where we didn't get what we thought we were supposed to get (I'm thinking it was only offered to the French players- could be wrong on that), so instead, we posted in a thread and our main dolls and alts received 150 feez, courtesy of a mod over our mods.

i see... thanks for the information, sierradane!
