Recently signs were placed on Eged buses all over Eretz Yisroel with the words: Moshiach Oseh Nisim (Moshiach Makes Miracles) and a phone number which people can call to ask for Brachos (blessings of the Rebbe-Almighty) through the Igros Kodesh. 
To promote the campaign, R' Avi Piamenta and his son have recorded a song to be used in Lag Baomer parades, radio and television advertisements, and much more. The song was composed spontaneously by a group of Temimim Farbrenging in Kfar Chabad...
