I am reminded that Pope Benedict does have a public email address: firstname.lastname@example.org
Now might be a good time to send a supportive and encouraging email. Obviously he is not going to read them all himself but it is possible that an official might let him know that there has been a number of loyal and kind messages incoming.
And do remember to pray for him. One way of reminding yourself to do this is to try to gain plenary indulgences as often as possible, fulfilling the condition of praying for the intentions of the Holy Father.
Remind others to pray for Benedict XVI.
