When I was home several of my loyal readers told me they did not know how to comment on my posts. So here you go!
If you go to the bottom of the post you might want to comment on you will see a counter that tells how many comments have been made about that post. That is a link. Click on it and it will take you to the comment page (some times it re-loads, some times its a pop-up so you might want to check on that one). Make your comment but make sure you type in the modification. I was getting comment spam so had to put that on.
Hope this helps!
