With the current contest that is going on, we've had several very cool Builds entered and I am enjoying seeing them all. There are a couple in particular that I try to "keep up with" as the write-ups progress. (For example, Rob Mahan's https://openbuilds.com/builds/robs-c-beam-machine-xlarge.6456/ and HC Carbo's https://openbuilds.com/builds/horizontal-minimill-x5.6349/ ) It would be nice if there was a "Follow" button (along with the like button) that I could click to get notifications when the Build Proper was modified. (And like the "Like" button, have it with the ability to "Unfollow" when I no longer want to receive notifications.) I "do" get notifications about discussion posts (if I've commented in the discussion section), but those don't tell me when the actual Build has been added to (and Rob's write-up is particularly well done). Anyway, I think this would be a great addition to the website.
