Because sending notifications in sites with many members can be a serious procedure, it seems unnecessary to inform people who have not been active lately. Thus, it is possible to "nullify" the notification settings for members who have not logged on in the past X days (where X is the number you enter on the appropriate form).

Load up the tools page and scroll down to the "maintenance" are for the "nullify notification settings for inactive members" tool (admin tool 173). There is a single field here, which you should enter a number of days in (if you enter nothing, 90 days is used).

What this does exactly

Theia contains a file used for creating the default notifications, and this is the same file used when resetting notifications. Thus, nullifying the notifications may not actually wipe them out completely, but resets them to default state. The file that controls the default state is found at:

DIR_CFG/default_notifications.cfg

This file contains special codes, which is exactly what appears in the notifications table in the database. They should look something like this:

[6.a]{6.a}[6.s]{6.s}[7.warn]{7.warn}[8.requ]{8.requ}...

How to interpret the notification codes

We have setup another document going over what the codes mean and how to understand them. You should go over it for info if you'd like to add or remove a notification to this file.
