By default, all end-users are encouraged to remain anonymous when they setup their user account, by ensuring that they chose an unidentifiable user name, leave their name blank and enter their industry rather than company in the company field.
All vendors, on the other hand, are asked to provide their real name, job title and company name, so that they are easily identifiable to all users.
If you need to change your user name, name, job title or company, you can do so by selecting preferences in the top right dropdown menu.
