Describe the enhancement and the motivation for it.
The new Slack integration in ReviewBoard 3.x is welcome feature. It would be even better if there was a way that would allow users to receive direct messages on Slack in the notifications settings instead of (or in addition to) email notifications.
This way they users don't have to monitor a channel filled with messages they may not care about.
