Can you subscribe to a Squawk without posting a comment?


I receive the email notification " A user has commented on one of your subscribed FlightAware Squawks." after I have posted a comment. There are times I’m interested in a topic, but don’t have anything to contribute. I am grateful for the ‘new’ icons, especially when there are over 100 comments and multiple sub-threads. Is there a mechanism to subscribe without posting that I just have not found? I found nothing in a search of the FAQ’s (but that does not mean it is not there).
