What should we call you?
When you registered you entered Flo. Camden's records say Florence. We have not changed anything.
Whichever you pick, this only sets a Preferred Name. It is owned by your Profile, is never sent to other systems as your official name, and you can change it at any time.
Why we are asking rather than just using what you typed
A registration name that differs from Camden's is at least as likely to be a typo as a preference. Promoting it silently would quietly rename you across every letter Camden sends, on the strength of one keystroke at sign-up.
