Di and I have arranged for me to post her letters to her blog. If you didn't know she had a blog, here is the address: dbmarie.blogspot.com. Her blog will publish the letters to her Facebook Notes section, so you'll also be able to read them there.
If you want to write her letters, here is her MTC address. It is good until the end of September (2011).
Sister Diane Marie Bowns
MTC Mailbox # 263
2005 N 900 E
Provo, UT 84604-1793
Send her some love and care! (And maybe send some for her companion too!)
P.S. In case you don't know me, I'm one of Diane's sisters.
