At the bottom of every post is a check box asking if you would like to track the thread, or is it track this post... Currently you can check it and follow the thread "if you post a response" to the thread. There were times when I didn't have anything constructive to contribute but am very interested in the responses. Because of vestibular problems and hence memory problems I may never recall the subject line in order to check on the thread at a later time. I'd love to be able to check that box irregardless of replying.
