My Mistake...instead of reading responses to my own post on the computer, I tried to read them on my phone :-(, whats worse is I didn't grab my eyeglasses.
So, when I clicked on the link at the bottom of the post in my iPhone...I suspect I accidentally "unsubscribed".
I reached this conclusion since I've not seen a single additional response to my post since reading responses on my iPhone...and now with my eyeglasses on see that the link at the bottom of the posts on the phone is to "unsubscribe".
So after all that explanation, the question is, how to I now "subscribe" back onto the list in general and to follow that particular thread?
Sorry to have created all this turbulence. Thanks for your guidance and explanations.
