 Sending kvitelach to the grave of a Rebbe or tzadik has also become a fund-raising tool. Mosdos Kever Rachel (Kever Rachel Foundation) encourages donors to send messages and prayers which will be read out at Rachel's Tomb. Similarly, the Breslov Research Institute website offers donors the opportunity to send a "digital kvitel" to be read by the grave of Rebbe Nachman of Breslov in Uman, Ukraine.
