kskad1,
Remember you are taking a risk by calling, but the news will be the same, whether you find out today or Friday, or next week. It's up to you. You can say you have patience if you prefer to wait, or you can say you have courage if you choose to call. Either way, you can see it as a strength and a choice.
When you call, ask for the staffer who handles the nomination applications. You may know that person's name from sending in your application. Look in your files or on the MOC's website. Don't ask for the MOC. Tell the staffer that you heard the list of appointees has been sent out to MOCs. Did Sen/Cong ____ receive it, and would it be possible to know if your name is on the list? Listen carefully if you applied to more than one SA. If you want to ask any other questions, I recommend you write them down in advance so you don't forget due to nervousness or excitement. If you are on the list, don't get so excited that you forget to say thank you. Use your best telephone etiquette.
If he/she can't tell you, it doesn't mean you're not on the list. Just means he/she can't share the info. You tried, but will have to wait. Good luck!
