's intentionally wanting to turn potential new members away
a valid description of the scenario of someone not getting their chosen nick approved on first try. This is something that will happen on all kinds of systems these days. You're rarely the first and you definitely not always have the option of checking whether your chosen name is avaliable beforehand. This is something I think people are used to, so it would not normally turn anybody away. Annoy for a moment, yes. But turn away, not normally.
On first thought FoxtrotUniform's nick up for consideration idea seems much more viable, but on second thought: What will some novice (or better!) think of the other monks if after some amount of time, they decide that he's had his nick long enough, just because he (possibly even unknowingly) hit too close to home? I wonder...
In my opinion, this option would have to be limited to something like the first 24h of a monk's life, at most. And even then, I still don't like it.
