You can click on your own username to get to your own personal forum usage information.
When you do that, you should get a page that shows different links on it, like Summary, Activity, and so on, across the top of the page, going from left to right.
When you click on Activity, you’ll see where your replies to posts are.
Some of us have avatars that we uploaded to the CAF website to use next to our usernames.
When you upload an avatar, it takes the place of the letter of the alphabet next to your username.
