I am just wondering if you can somehow "share" your my PLAN with others on the forum so that they can suggest things I might need to improve, or whatever?

Yep. Just click on "edit settings" (on the left) and you will see where you can change "No one may view my logs" to "Other forum members may view my logs."

Once you have done that, you will have a little MyPLAN icon at the bottom of each of your posts, and other members can click on that to see how you are doing.
