disable uppercase and spaces in the display names

[OptimusBain]

Hello,

Is there a way to disable uppercase and spaces in the display names? Some users are using upper case and even spaces in a two words display name. Is there a way to control/disable that?

Thanks

The settings are under ACP → Members → Profiles → Profile Settings → Display Names → Allowed characters in display names

I think in your case, you would have to switch to RegEx mode to only allow the a-to-z range without spaces or uppercase.

Hello everyone, any ideas to prevent the full name from being capitalized?

This would be valid: Name or name
This would be Invalid: NAME
