Hey Bill, I think he was reffering to advanced standing re-applicants ... or was he ? I don't know.
Anyways ME2005, in case that you were asking about advanced standing re-apps., than you need to contact each school prior to your "re-application" process inorder to determine specifically what they require of you, as due with their policies.
Every schools is different. Some schools may require a whole new application & supporting documents (scores, recc. letters, fee ... the whole nine yards), while other schools may just ask you to inform them of your decision in writing to be considered for the following years applicant pool.
Sometimes even if they don't need any additional documents from you, it's always a good idea to check with that school if any of your application material has "expired". Usually the expiration dates are as follows:
Application and fee 1yr
Reccommendation letters 1yr
TOEFL 2 yrs
NBDE 5yrs
I hope this helps, and good luck.
