If so, and you can find a free one on somewhere like www.aspin.com, then use that.<BR>3) Can you code in Perl? Does your host support Perl? If not, you can't use Perl.<BR>4) Can you code in ASP.NET? Does your host support ASP.NET? If not, you can't use .NET.<BR><BR>So, yeah - you need to do some research, that's where to start :-)<BR><BR>Craig.
