Today I discovered a very useful feature that you might want to be aware of.
If you go to any board on the forum, and then click on the Actions dropdown menu on the top-right, you can set Notification Options. Using this, you can set to be notified via email either instantly, or daily, or weekly.
With how little activity the forum sees on average, you might want to take the time to set up those Notification Options on every board, so that you can know straight away if someone posts something there.
Alternatively, you could go to your profile settings and set those notifications up for the whole forum, which should save the time you'd otherwise spend setting it up on every board individually. Go on your profile and hit Edit Profile as shown in this image and then just go to the Notifications tab.
