Cannot convert account to organization

Hi there,

I’ve just create this account - hs3city and right after that I’ve realized that an organization would be a much better fit than a plain account -> therefore I’ve attempted to convert this account to org, but when I’ve entered the user I’d like to be the owner (allgreed), nothing happens. If I type hs3city or non-existent username I get an error. The Javascript console looks clean. I’m using Firefox 58. Is there something I can do?

Regards
