westor thank you

I made a quick function that might be useful:

; Know if a nick is using an account with $true or $false : //echo -a $isAccount(tapavu)
; Know if nick uses an account, if yes it returns the account :  //echo -a $isAccount(tapavu,1)
; If the account does not exist, then $false : //echo -a $isAccount(FakeUser)
alias isAccount {
  var %account = $ial($1).account
   if ( %account ) {
     if ($2 == 1) {
     return %account
     }
     return $true
   }
   else {
     return $false
   }
 }
