Hi Scott
There's an example of how to save content in static HTML buried in the control panel: in the "tools" tab there's a big green button to "Download all tiddlers as static HTML". Clicking it should download a static HTML file containing all the non-system tiddlers concatenated together in alphabetical order.
The code that creates the button is in "$:/core/ui/ControlPanel/Tools":
<$button message="tw-download-file" param="$:/core/templates/alltiddlers.template.html" class="btn-big-green"><<lingo Export/AllAsStaticHTML/Caption>> {{$:/core/images/save-button}}</$button>
In order to change the tiddlers that are included, and control their ordering, you can overwrite the filter in "$:/core/templates/alltiddlers.content":
{{{ [!is[system]sort[title]] ||$:/core/templates/static-tiddler}}}
Best wishes
Jeremy
