Did anyone else NOT get confirmation letters from UCs?

I applied to 6 UCs, but I only got 4 confirmation letters so far. should I contact them or just wait?

<p>No, it's probably all right. Some just don't send out confirmations (like UCLA i'm pretty sure). If you know that 4 of them got your app, the others probably did too, since its all on the same computerized system.</p>
