A better workaround than “none” would be the company “Individual - No Account” (https://nonameaccount.com). Please note this really is just a workaround/hack, but it does the correct thing in the backend, as this is treated in multiple places as an unaffiliated individual, unlike “none” or the many “individual” company entries.
Henry has already posted this but I’ll mention again, that in terms of being able to change company yourself, I’ve started a discussion on this over in Feedback for next iteration of committee/project user management. And in fact seeing that I didn’t mention anything about individual contributors, or making title optional, in that proposed spec, your feedback on those areas would be much appreciated!
