Notify of Squawk update w/o posting comment

If you post a comment to a Squawk, you are notified when a new comment is posted. Is it possible to register to follow a squawk without posting a comment? If this capability exists, I have not found it. If is does not, would it be practicable to implement?

This would avoid the risk of an acerbic comment by Peter F Hartmann, Esq about non pilots ‘polluting’ the comment space.
