Theres no need for all the on text events, can be compiled into one.
on 1:TEXT:*:#ComputerSupport: {
if ($1 == !slow) <command>
if ($1 == !Protection) <command>
if ($1 == !FrostWire) <command>
}
also,
notice $nick Your greet message has been set to: $2-
Putting a '.' before notice makes it silent so it wont show on your window you sent the notice. But it will show the $nick that you are noticing.
