Common people, so far only corrections have been added, where's the hint systems!?! :tongue:

Here's one from me.

; Usage: $Nfirstletters(<string>,N,<char>)
;
; Example: //echo -a $Nfirstletters(this is a test,2,?)
,
, -> th?? is a te??
;
; Shows the N first letters of each word in the input string

Code:
alias Nfirstletters { 
  var %a, %b = $regsub($1,/(?&lt;=\S{ $+ $2})\S/g,$replace($$3,\,\\,$,\$),%a) 
  return %a 
}
