That usage was adding a blog to a Saratoga template site and that can be done fairly easily.
If WordPress is your primary site, then adding Saratoga template stuff via direct include (not iframe) can also be done, but it is much more tricky. You'll need a plugin in WordPress that allows you to run native PHP code (like
Insert PHP). Then you can add various things to posts/pages on your WordPress site.
You may have to adapt some Saratoga scripts (like adding an include for Settings.php and common.php ) to make them work without the normal wx....php page infrastructure.
Scripts from Saratoga designed to run standalone (like the forecast scripts, etc) can likely be used via Insert PHP in a page with only customization of the inner settings in the script.
Hope this helps...
