Hi @chilepower,
The “Username” and “Name” fields are two different fields. The first one is a unique username that is used to login, and to mention other users in activities and such (for example: @username). The second one is supposed to be the real name of the user. Both are required for BuddyPress to function properly.
Please note that Gwangi is not responsible for the registration form and fields, as everything is handled by the BuddyPress plugin. So if you still want to remove the “Username” or the “Name” field, I’m afraid you’ll have to either contact BuddyPress support (https://buddypress.org/support/) or hire a developer for custom work.
Best regards,
