what's the whole point...
that's like a something straight out of a bot. if you are lame to some MSN Bots they start doing stuff like that.
ontopic now:
1st of all: /warn = impossible, /xwarn possible (unless you use /xwarn in a quiktext with the alias /warn)
2nd: Making registery keys for something that useless. if you have 150 contacts they all need there own key!!!
3th: That's really complicated!
4th: tag's like (!NP) can't be used in plugins (check the API)
5th: try working on your english
(typt => typed)
6th: I'm not going to make it!
TIP:
try Gilly Messenger. you can make scripts for it that could do what you want.
* crank opens up EDITPlus! 2 and starts making a GMS warning system.
* crank thinks that he will not do this as he is modifying a hangman script for his Gilly based MSN Bot...
EDIT:
* crank had to much time
I made the Gilly Messenger Warning Script v1.0.
