Apparently it is time to repost instructions, as many of us seem to have forgotten.
Step 1: Click on the words at the bottom of the post that read "not a single comment yet. sad." or "one lovely and intelligent comment" or "# words of encouragement, thus far".
Step 2: A little pop-up window will pop-up. Don't be alarmed. It is a nice friendly pop-up window eager to receive and cherish your every utterance.
Step 3: Type your name or alias into the name box.
Step 4: Type your email address into the email box (no-one will see it but me and you can always type in a phony one if you wish).
Step 5: Type your comment into the box that reads "comment".
Step 6: Click the "Preview" button; admire your contribution.
Step 7: Click on the "Publish" button.
Ready. Set. Go.
