I'm making a cake w/ raspberry filling, and will be covering it in fondant. I've heard that you shouldn't refrigerate a fondant covered cake. I'm worried about leaving the cake out however, because of the fruit filling? I'm positive someone has had previous experience with this. Any advice you can provide would be appreciated! Thanks!

If you need persuasion, here are 2 links- 1 is a thread where they talk about it here in cake central, and the other is the link to Country Kitchen's sleeves ...
