Confirmation of new theme designer approval email

I recieved an email that I was chosen as new Galaxy theme designer.
I have a question about Security pledge. I have to write there my company name. Can I write my seller’s username instead? Because I’m a private seller.

Congratulations! Yes, just put your name on there.

if I have already written my personal name on a separate line, do I need to leave this field blank?

Also if I want to sell themes should I change my status
