My question is: can I set the Company name field in new user registration form to max value to: for example 200 signs

In my area (Europe) company name could be very long, for example:
"Przedsiębiostwo Handlowo Usługowe Import-Export Janusz Kowalski"

Now, I can only type 32 signs in that company name field, it's not enough.

I didnt foud that in Admin-Configuration-Max Values

Maybe I can deal with that problem by editing some files?

Thank you and sorry for my english;]
