Username Regular Expression restricting a user not to use only numbers

[kushal]

Hello community,

I am looking for a solution in which a user is not allowed to use only numbers in the username.

It is fine to use


andy
andy12
12dandy
andy 123


But I do not want a user to use only numbers as in '232323110' in the username.

Can somebody help to define the rule?
