Clarinet Transformation Community looks a little different on small screens (mobile devices) and large screens (desktops and laptops). Most of the instructions on the site use pictures of large screens, so may be a bit unclear to mobile users.
Another difference is that on mobile devices you have a choice of using the Circle App or the ordinary web browser. Most experienced users prefer to use the browser version which has more functionality, particularly for uploading videos. All pictures here based on browser version.
Here is the story in pictures. Approximate, since I see a little more as an ambassador. Also, screen elements can move from place to place depending on your specific device.
Big Screen
Figure 1. Large Screen

Figure 1 Legend
(1) The menu
(2) The post area
The menu is divided into “folders”. These folders are collapsible. The icon (3) indicates whether the folder is collapsed. V means it’s expanded. > means it’s collapsed, and you have to click the arrow to see the contents.
(4) Shows the Meet with an Ambassador link. When you click that link, the appointment calendar shows up in the post area.
(5) Non-clickable label showing which major section of the menu is actie.
Smaller Screen
There isn’t room to show everything on a smaller screen, so there are extra functions to select what to show. Here are some examples:
Figure 2. Smaller screen with menu hidden. Only the post area is visible.

Figure 2 Legend
(1) The menu is hidden — click this icon to show it. The menu icon is at the very top left of the screen, so you may need to scroll up to the top to find it.
(2) There is a menu of icons at the bottom of the screen: Home, Search, New Post, Notifications, and Direct Messages. These functions appear at the top left of the large screen.
(5) This is the same as (5) on the large screen — it’s a label showing what section of the menu is active.

(2) When the menu is showing, click this icon to hide it. You can also hide the menu by clicking in the post area.
