Using your example:
Code:
 on *:TEXT:!test:#:{
  .timertest 1 5 { test # $nick }
  .timertest2 1 5 { test2 # $nick }
  /halt
}
alias test {
msg $1 alias 1 found $2  
  ;WRONG - msg $chan alias 1 found $nick 
}

alias test2 {
var %chan $1
var %nick $2
msg %chan alias 2 found %nick
 ;WRONG - msg $chan alias 2 found $nick 
}

To read more about aliases, type " /help aliases " in your mIRC client. You can also read about variables by typing " /help variables " in the same way. Variables always start with a % in their name.
