If you’d like to send a letter to Elder Leake without buying a stamp, go to DearElder.com. Sign up for a free account and then write a letter which they print and deliver. Right now, Elder Leake is at the Provo MTC and you’ll need his current mailing address (see sidebar on right) to get it to him properly.
Later, when he ships to Mozambique, you can send letters to him via the weekly pouch. If you have any questions, feel free to contact me at hsleake at gmail.com.
