In forum settings, I have enabled minimum 4 character for display name.

However users can register with just one character in display name.

BTW, is there a setting to have minimum characters for username? I was able to have 1 or 2 character in username. I only found setting for maximum character in username. I also did not find setting to have maximum character for display name.

Overall: Can we have the following four settings:

1. Setting for minimum characters in display name
2. Setting for maximum characters in display name
3. Setting for minimum characters in username
4. Setting for maximum characters in username

BTW, is there a setting to have minimum characters for username? I was able to have 1 or 2 character in username. I only found setting for maximum character in username. I also did not find setting to have maximum character for display name.

Both Settings for minimum / maximum chars. are applied to user name and display name. At least for maximum length. For minimum length it was not the included.

Updated code is online now it checks for user/display name min. and max. during registration and on the profile page.

I also moved the Settings for min and max in to one place in the host settings
