[nas]peter afk script.
To install follow these instructions:

Go to the Tools menu and select "Scripts Editor" (press ALT + R at the same time will immediately go to "Scripts Editor")
Select the "Remote" tab
Select NEW in the FILE menu
Copy + Paste the entire script into the resulting file
Click the OK button
Right click on a channel
Go to "AFK script and Nickalert (or AFK script if you didn't get nickalert integrated in it)"
Click "AFK dialog" and a dialog will turn up
Click: "Install script" and fill out all prompts

P.s. I can't get autoafk to work (someone told me this would work:

; alias checkaway {
if($idle > %autoafk.time && %afk.status == off) {
  Afk-on Auto afk after $duration(%autoafk.time)
}
;if($idle < %autoafk.time && %afk.status == on) {
afk-off
};

i saw it was wrong as you can't normally go afk.

set %afk.status 0

}
alias afk-off { set %afk.status 0
