What happens to @pontifex after Papal resignation?

In response to numerous queries as to whether the Holy Father's twitter account will be permanently shut down following his resignation, Msgr. Paul Tighe, secretary of the Pontifical Council for Social Communications issued the following statement:

The Twitter account @pontifex was created for the exclusive use of the Pope.

@pontifex will be inactive during the interim period between the renouncement of Pope Benedict XVI and the election of his successor (sede vacante).
 
@pontifex will be available for use by the next Pope as he may wish.
