so, a lot of the people giving advice to us waitlisters have suggested sending letters to the deans/admissions directors/whoever about every month or so.  i'm planning on doing this for one school in particular.  i've already sent in a letter of intent about a month and a half ago.  my question is, after the letter of intent, what kinds of letters are these that people send each month?  just updates?  reiterations of the letters of intent/interest?  it seems like there would be a pretty fine line between something meaningful and then something that is just plain pestering.  let me know what you guys think or have done in the past.  thanks!
