Your profile is created when you set up your Clubhouse account and your Full Name, Username, and UTC Offset (used in Email Notifications and Reports) persist across all your Clubhouse organizations.
Setting Your Mention Name
Mention Names and Full Names.
Setting a mention name is optional. Mention names are unique to each Organization of which you are a member, meaning you can set the same mention name across all of your Organizations, or choose a different one for each.
If no mention name is set, your mention name will default to your Clubhouse username.
You can update your Full Name, Username, UTC Offset and your Organization-specific profile icon by going to Settings > Your Profile. This can also be reached on the Clubhouse Organizations Page (more on that here - The Clubhouse Organizations Page).
Setting Your Profile Icon
Your profile icon is Organization specific and is set everywhere in the Clubhouse Organization where you are listed as an Owner, Follower, or Requester. It also appears where ever you leave a comment or make an update.
By default, Clubhouse will use either a colored circle or the image associated with a Gravatar account as your profile icon. If you wish to set your Profile Icon, you can do so by going Settings > Your Profile and then clicking "Upload Icon".
You will then be prompted to upload (and optionally crop) your image.
Once you are satisfied, you can hit "Upload" once more to set the new Profile Icon.
