I know how to edit, delete and put back the notebook files, and how to
change to weekly log files. But if I switch to weekly, can I then delete the
monthlies, chop them up, and put them back as weekly ones. This way I could
keep the past consistent with a switch to weekly.

Or maybe I could leave as monthly, then after the month is over chop them
into half-months? While I prefer monthly, Juno subscribers can't receive
e-mails greater than 64K. Any chopping up would be to reduce them to below
this threshold.
