 ### Gallery and Catalog
 
+PreTeXt has been used to create a large number of Open Educational Resources.
+
 The [Gallery](https://pretextbook.org/gallery.html) is a small collection of mature PreTeXt projects that demonstrate the range of features and the diversity of subjects.
 
 The [Catalog](https://pretextbook.org/catalog.html) is a comprehensive list of PreTeXt projects. You can get a sense of the possibilities, and where authors have public source, you can look to see how certain constructions are authored.
 
 ### Starting Out
 
-The [Documentation page](https://pretextbook.org/documentation.html) has information on Getting Started, the full documentation (The PreTeXt Guide) and additional resources.
-
-### Community
-
-Authors, publishers, readers, and developers congregate on Google Groups (in addition to GitHub issues once discussions are resolved). The support forum is the easiest, quickest, most accurate way to get help from experienced authors, publishers and developers, even if you are just starting out, and have only read the [PreTeXt Guide](https://pretextbook.org/documentation.html) once.  Every PreTeXt author should subscribe to the announcements forum since changes and new features are broadcast there.
