Answer
The ability to force all users to receive a list as digest or to change the time a digest is sent at is only configurable with the full version of GMS Communication Server. There are many other functions only available with GMS Communication Server as opposed to the basic list server, including moderation, personalisation of postings and so on.
28 day trial keys for GMS Communication Server are available from sales if you wish to trial this high performance software on a test machine to see what functionality you are missing out on.
