Optional settings from the registry entry, left out of the block above:
MESER10_USER_ID (Meser 10 account number. Not a secret. Optional: 17 of the 61 operations authenticate on the key alone, the other 44 need it), MESER10_MODE (Safety gate: read (default), write, send or destructive. Each level adds tools; send delivers to real recipients and spends credit), MESER10_MAX_RECIPIENTS (Refuses any single send targeting more addresses than this cap).
