BuddyPress.org

Hi
I know these posts are really old, but does this still work? I’m not quite sure how I really have to do it?
So can maybe someone help me with it please?
I want to hide the username field, and would like to auto-generate the username based on the normal “Name” field in BuddyPress.
So that WP and BP automatically take the first and last name out of the “Name” field. e.g. Name field input: George Smith username: georgesmith

I already have the plugin activated that user can login with their email address.

Thanks for help!
