Redmine

This plugin enables you to send and receive daily/weekly/monthly digests.

To create a digest rule, click My account and then click New digest rule.

Specify the rule name, select which events should be included in a digest (all options are enabled by default) and configure other options as necessary.

A detailed digest displays both the changed and new values, shows the time and author of the updates.

You can create as many digest rules as needed. You can also preview, edit or delete the created digest rule on My account page.
