Thank you everyone for your responses! Most who shared are normalizing dates (or wish they were). I'm going to look more closely into Jason Casden's PERL script, but I haven't worked much with PERL before. I installed ActivePerl, but can anyone advise me on installing the necessary XML::Twig and HTML::Entities modules? I found the website for XML::Twig, but don't know how to install it as a module. Thanks again; this is a great list! Nathan On Thu, May 6, 2010 at 9:29 AM, Nathan Tallman <[log in to unmask]> wrote: > Good morning, > > I'd like to take a quick and extremely informal survey.
