Forums Scripts & Popups regex help

I want to kick only if the nick is not longer then 4 letters??
($regex($nick,/^[a-z]{1}[0-9]))

Use the pattern ^.{4,}$ , put it in a variable (because of the ",", if you put it directly in the $regex, mirc will consider it as a third parameter).I use . to match anything but you can be more precise if you want

exemple please?

change GaisGa to Gais and to Gai to see the difference
