Hi guys,
With this script I want only accept the .NL and .TK country codes. Other country codes are not allowed and that works fine with this script…
BUT I also wants to bann some domain names like Hotmail, MSN etc…

See:
=======================================

/* The following is the list of banned domains */

var bannedDomsPat=/^{^(hotmail|icq|yahoo|freemail|msn)$/;}
=======================================

Can someone help me to fix this into this script, plz???
