Hey all! At the top right of every thread page here on the forum is a row of options - "Reply", "Add Poll" "Notify", "Mark Unread", "Send This Topic", and "Print".
If you haven't used those before, you may find that "Notify" is a much better way to be emailed notifications of new posts on threads you follow. This allows the LBS whose thread you're following to have full use of their 150 posts for their own journaling and feedback from all of us, without needing to scroll through empty "attaching" messages, or start new threads earlier.
Of course, if you still would like to welcome them to their new thread with a message of hope and support, or input for their thread topic, that would help maintain the integrity of the forum as a whole as a means of valuable support and information for us all, and show great LBS solidarity!
