I don’t know if that’s possible, Robyn. I’ll have to look into it. But honestly, if you really want to stay on top of things as easily as possible, you might consider just subscribing to the RSS feed for the blog. It’s the little orange button at the bottom of the page. You can subscribe to the forums as a whole by clicking the icon on the main forum page or you can subscribe to each individual forum. It won’t show all the replies, but if there is a thread you’re interested in, you’ll likely just subscribe to the email notification for that thread anyway.
The cool thing about the RSS feed is that you can use a feedreader program to see if there’s anything new on the forums OR on any of Shaun’s blogs (or any of the other blogs you read).
