TVD Season 6 starts being prepared today

According to Julie Plec last tweet, today is "day one of preparation for #TVDS6. A fact that makes me happier than you could imagine. This season is going to be amazing." 

Does it mean they start filming today? everything points out that YES. Some TVD actors and writers have already made comments about how amazing and touching season 6 start will be, they have already seen the scripts, so everything indicates that now they will start filming today.

So be prepared, TVD fans, because we will start having spoilers more often from today. And we will be here to comment them and to speculate about them!
