Ask Stacy Blackman

It seems business schools require two or three recommendation as part of the application. I have no problem getting them for a school. However, I'm not planning on applying to one school but as many as ten. And I am not sure how to approach my recommenders to complete this daunting task for me (it's one thing to ask for one recommendation). I'm wondering how other applicants have tackled this problem. Should my recommenders make their reference letters generic enough so they can use a single composition for all schools? Please help.
