When you are admin and need to kick/ban someone from your server wouldn't it be useful to be able to just type why you did it and have it displayed on the screen? Like, X is spawnkilling and I want to kick him for it. I type 'spawnkilling' in textbox labelled 'Reason'. And press 'Kick'.
Or type in console:
kck 6 "spawnkilling" (assuming he has id of 6)
What X sees is:
You were kicked. Reason: spawnkilling.
Also in the main console everyone could see:
X was kicked. Reason: spawnkilling.
Advantages:
-That would save everyone's time, as kicked banned person would not need to ask why.
-Others could see it and take it as a warning
Disadvantages:
-Someone needs to implement it. Some may argue there are more important things to do now, but this one would not take long to do methinks.
