I've "google"-ed, checked the list archives, and looked at the period.conf man page, but I can't seem to find a way to do what I want. However, I'm sure I'm not the first person to want this functionality.

I don't think the periodic scripts have that capability.  However,
it's fairly simple to get a list of all logins on the system (except,
for some unknown reason those logins via xdm(1) and similar graphical
login managers).

The command to use is last(1) -- note by default that reads
/var/log/wtmp which is recycled each month via newsyslog(8).  You can
edit the /etc/daily.local script to get that output included in your
daily e-mails.
