The neighbourhood house where the Mac User Group holds its monthly committee meeting recently changed its wifi hotspot's SSID & password. We'd been told via email that the new password was "L1f31saWonder," with a mnemonic of Life-Is-a-Wonder. It didn't work when we tried it.
There's a sign-in book at the venue, we discovered & in it was the actual password, being "L1feiswonderful." This one worked fine.
Life is wonderful when different branches of an organisation are working from the same page.
