The client was super, super pissed.
Anyway, yes, we do use the whisper feature, too much in fact. But that particular time we thought we were clear. In fact, we use the whisper so much that I am thinking about modding it a tad via a plugin, as I find that:
- For someone who whispers a lot (most our admins do due to the nature of our site), we find it cumbersome to click two times to get to the option.
- Quite often admins become so numb to the feature (routine?) that they forget to turn whisper on. I plan to change the button to a different color (the submit button) once Whisper is picked. It’s easy to forget yourself (that Whisper isn’t on when replying) and then look like crazies when our members see these messages.
