Congratulations on taking the first step toward becoming a Peace Corps Volunteer. Your application packet was received by the Denver Regional Office today. It is now being reviewed by a recruiter based on your education, volunteer and work experience, life skills and hobbies. You should receive a letter regarding the results of this review in approximately two weeks.
Now I'm just awaiting my toolkit info letter and a call from my recruiter to set up an interview!
BTW - "toolkit" is (from my limited understanding) an online program where I can track my progress and download any additional forms/information.
