First congrats =]
Well after you get the paper signed and stamped, you need to go to get yourself in listed in the DEER's program. Which is the health insurance. Then get your military I.D, and have your hubby get you in his WILL. I believe that's about it. You do all that on base, they should tell you what to do. They helped me =]
Don't let these people on here freak you out. Good Luck!!!
