Sadly, the blind function was a bit broken. I blinded one of them for a bit, but it seems that you can't unblind them later. So it seems to be buggy in this sense 
The blind function works for a set duration (usage: blind <player> <value>) or until they are killed, whichever comes first.
I was playing with admin controls and cvar adjustment as well overnight (with BSoD and Shady), much to their chagrin. :V
We can't set server password though.
EDIT: On another note, YER with standard watch is freaking brilliant...kept stabbing opponents and forced half of them to go Pyro. I'm normally a DR user, though, but it's a bit harder to use that when there's no disguising function to better fool things around. :V
