A temporary list for late entries, until added to proper list

     This will be a temporary list, for situations when an e-mail has been sent out to a large list,
and, afterward, additional e-mail addresses are presented to which the e-mail needs to be sent. 
The purpose of the temporary list is to prevent having to constantly create new lists for that
purpose (or sending out an additional identical e-mail to the members of the group to which the new
names are added).
