Regardless of whether you're using the ActiveState build of Perl for Windows or not, ActiveState's Web site at www.activestate.com is a great place to start for help getting started with Perl for Windows. From there you can find the ActivePerl FAQ at http://aspn.activestate.com/ASPN/Perl, and the various ActivePerl mailing lists at http://aspn.activestate.com/ASPN/Perl/Mail.
ActiveState also offers support for their version of Perl. See http://www.activestate.com/support/ for details.
And, of course, the standard Perl resources are always available at www.perl.com, and pointers are scattered throughout this book.
