The email we got from stardoll explains it all:
So now there is another trophy you can get on stardoll. There is bad side to this change, most party rooms cost 5 stardollars, although three are 0 stardollars I think stardoll had this idea from the start when they introduced parties because they would tell you that it costs 0 stardollars to make a party. Do you think this change is for better or for worse?
Another change stardoll made is that when you go to your album there is a tab named photos where you can view the photos you have taken. You used to only be able to take pictures in parties, but now you can take them in your suites!! I like this idea.. you can take pictures of your suites and outfits and never lose them :)
