HOW TO POST
Click on either the "comments" button at the top right of this post or the bottom left. Either one. Fill out the name and email portions of the dialogue box when prompted to do so, and then post your 200-250 words I that space. Click "submit" and you are done.
You can "reply" to a specific post from your colleague by clicking on "reply" rather than "comments." Don't worry if you accidentally post something in not exactly the right place.
