Question for Gumbo users

HI this is actually applicable to other uses. W/ Gumbo, any programmer often 
goes in and adds a report and subscribers ( Gumbo links the spool file, to a 
user email via the DIRE).
Sometimes, we hold all the subscribers for a particular report when we need to 
resend to one subscriber. Sometimes we forget to release them. (there is hardly 
any other way to do this). At any rate, I would like to get a report at the end 
of the day, illustrating any changes made to the Gumbo system. Perhaps someone 
has done this or has any thoughts on how to do this?
Thanks,
Jay
