Restrict Usernames\Thread Titles

[alkuwary]

Hi,

Is there a way to restrict Usernames to english only and also thread titles ? I tried searching but didn't find anything for vb 3.8.1

TIA

Add this as the username regex (Admin CP > vBulletin Options), it will allow only alphabetical characters.
^[a-z]+$

How about only allowing alphanumeric characters ?

Also I can't do anything about thread titles ?

Thanks for your help Dismounted, It's highly appreciated.

^[a-zA-Z0-9 ]+$

Alphanumeric (Both uppercase and lower) characters including space

Thanks I figured it out now and modified it a little bit so it will allow underscores and not spaces, here's the code if anyone needs it.

^[a-zA-Z0-9_]+$

If you need to add spaces here's the code

^[a-zA-Z0-9_ ]+$

What I need now is a way to restrict thread titles also, Can anyone point me in the right direction ?
