I am aware that many of our missionaries have public blogs (my own daughter included), but there are some guidelines that should be followed in missionary blogs to help keep our missionaries safe.
Hermana Klein from the Honduras San Pedro Sula East Mission has written a wonderful blog post explaining these guidelines. If you are keeping a blog for your missionary son or daughter and are posting their letters online, please go to the link and read Hermana Klein's post. All of her guidelines are applicable to Mexico as well.
Just don't get jealous over how awesome her blog is.:-)
