After putting up this post, I realized that too. I guess having them listed as what seemed to me as different transactions in the `recenttransactions` call confused me a bit. Thanks!

<p>I originally thought one could determine whether a transaction is unique or not by its id. However, if you perform <code>sendmany</code>, then each of these transactions will share the same id, is that right? In this case, how would you go about determining if a transaction is unique?</p>
