The technique is to create Google Docs documents and then publish them via the command File>Publish to the Web.
When you use published Google Docs documents, several things become possible for FTH websites:
1. Your document is converted to a view only web page. This is useful as embedded features such as hyperlinks are preserved.
2. If you update the Google Docs document, then the published version is automatically updated. Useful as an approach for club newsletters.
3. You are provided a web page link to your published Google Docs document. This web page link can be used as a custom link in the FTH menu structure.
4. You are provided iframe html code that you can embed in FTH custom webpages. You could use this as a approach to embed a newsletter in your website without requiring your members to learn the ins and outs of editing your website's webpages. They can just use the Google Docs document editor or they could probably also copy and past from Word (I have not tried this yet).
As a demonstration of this approach here is a link to a published version of a Google Docs document that I created specifically to demonstrate this approach. (Try out the links on the page.)
