Registration Referrals Report (/admin/usersregistrationreferralreport, no menu link) — a distribution table of every referral source with its percentage and count of registered users, plus an "Other" row for users who picked "Other" and typed in their own answer. The percentages are calculated only among users who actually answered the referral question — someone who registered without answering it (for example, before the question was turned on) isn't counted in this report at all. Click any row to see the list of users who chose it, with their name, any free-text "other" note, and registration date.
