If you want to let your user change their avatar, edit their profile, modify their names, or you want all the guests to show their “Edit profile panel” when they enter the chat room for the first time, you can set your settings to achieve all these on the current panel.
1. If you only permit the users to choose their avatars, please check the “Switch Edit profile to Change avatar”.
When it is checked, please take a look at the below screenshot.

When it is not checked and the “Enabled to change nickname” is checked, it shows that you can modify the nickname.
When it is not checked and the “Enabled to change nickname” is not checked, it shows that you cannot modify the nickname.
2. If you want the system to popup the “Edit Profile” panel, please check the checkbox “Pop up Edit Profile panel when a guest enters”. Meanwhile, the “Enable to change nickname” checkbox must be checked. If the username begins with the text of the “Pop up Edit Profile panel for the guest whose name is initialized with”, this panel will be popup. If the text of this textbox is empty, it will produce the same effect whatever the username is.
