Unsubscribe users from courses after
To help keep lists of participants up-to-date, you can tell Moodle to unenrol any user (student or teacher) who hasn't logged in for a certain amount of time. Be sure to keep this time long enough so users aren't unenrolled accidentally while they still need access to the course.
Delete unconfirmed users after
If you're using Email-based self-registration users must confirm their account within a certain time-frame. Once the time set here has passed, any account that hasn't been confirmed will be deleted. 7 days is a good setting.
Delete incomplete users after
In Moodle 1.9.2 onwards, the period after which old not-fully-set-up accounts are deleted may be set (from 1 day to never).
(What is the definition of a "not-fully-set-up account"? What criteria needs to be met for an account to be fully-set-up?)
Keep logs for
Moodle keeps extensive logs of user activity. Eventually, however, the logs will become so large that they begin to clog your server. Limiting the length of time logs are kept for will reduce database table size. Generally, a year is enough time to keep logs for.
Disable grade history
In Moodle 1.9 onwards, history tracking of changes in grades-related tables may be disabled by checking the disablegradehistory box.
Grade history lifetime
In Moodle 1.9 onwards, the length of time that the history of changes in grade-related tables is kept may be set (from 30 days to never).
