no, i dont wanna read to find out how this thing works, just tell me where to get _____
fserv script spam
infected user spam
fserv scripts that hex mIRC and screw up something else that then needs fixing
why wont this fserv script work and why should i go ask the person who wrote it, you're supposed to fix it.
HELP, i'm infected, fix me, its mIRC's fault
