Display name restriction with space allowed

[Black Tiger]

Hello.

I don't like arabic and other strange or special characters or e-mail addresses as a username. But I do like if the user can use spaces.

Now I found the Display Name settings in the profiles.

So a setting of a-z0-9-_ would allow a-z (lower and uppercase) 0-9 in numbers and - and _ characters.

But how do I define that a space is also allowed in the username? Do I just enter a space like a-z 0-9-_ or how is that done?

'a-z0-9-_ '

Thank you.

Do I need to put that between those apostrophe ' characters?

[Rhett]

yes, note the space at the end.

Yep I did, thank you!
