Thread: Can a new user registration name be anything?

Can a new user registration name be anything?

For example...

1. is there a length requirement or limit?
2. can parts of their user name be capitalized like as if it was a company name? example: "General Motors", can that style be a user name?
3. can there be spaces in their user name?

any other insight that can be offered is certainly appreciated. have a great day
