Re what does HDR stand for, Hilary was christened Hilary Diane Rodman at birth.
Again, I see no ‘normal’ admin going through the history of their client to setup mnemonics based on BIRTH names; let alone appending whatever numbering system devised, for a group of (let’s say) 10 users.
At best, it’s a waste of taxpayer $$ (admin/time), at the worst (which I’d wager), nefarious means of obfuscation and deceit.
