This is a variation of my last snippet "Random Temporary Nick" and allows users to actually store an unlimited number of alternate nicks in a file called nicks.txt rather than using a random nick, eg nick354

;;;; Unlimited Alternate Nick Script 
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

;raw numbers defined
; 432- Invalid nickname
; 433- Nickname in use/nickname registered
; 451- haven't registered

raw 432:*: { .altnick }
raw 433:*: { .altnick }
raw 451:*: { .altnick }
alias -l altnick {
  inc -u10 %neednick
if (%neednick >= 2) { tnick $read(nicks.txt) } } 

; end of snippet
