Maybe we could try and make it so that you're not allowed to use set messages as notice of attack and if proof is obtained they could be sanctioned for doing so whilst limiting the amount of setmsg's to 3 so that people, like thunderer, can use them to identify them selves.
Also I remember setmsg being used to spam chats rather intensely in the past.
I'm kind of in favour of this. But at the same time I see the value of keeping Setmsg and allowing the use of macros to paste messages.
But yes using it to quickly give notice of attack when someone is mid sentence and dodging all possible RP kinda sucks. I might not RP on the forums too much if not at all but in game it's just:
"You're evil. "
*setmsg with notice of attack*
