Where did you see a promise that users could add to the help?
What words have you interpreted to mean that?
On page 24 of the RH11 User Manual, it says, "
Create a knowledgebase that has an interface similar to a wiki page. The knowledgebase project template contains master pages that you can customize. You can also create self-updating pages.
I'm looking for a project separate from my regular Help that nobody but me can update to a Wiki where users can post their own best practices and post questions and answers, in some ways much like this page.
I will need to refer to Adobe to understand their thinking there. You can put an iframe in a page showing content that will show the latest information rather than the information when you created the help, in a way that is self-updating. However, I cannot see that is the same as a wiki. I will ask the question but it is likely to in the new year before there is any response.

Okay, I found it in the help. FWIW, it's also mentioned when creating a new project.
What this is referring to is that the project template will create and offer a page that never needs maintaining. The page is labeled "What's New", and describes a method of using See Also keywords to manage new and changed topics. If this method were not used, a "What's New" page would require creating links or specifically adding verbiage about each new topic.
It DOES NOT allow creating one or more pages that users may contribute to.
RoboHelp has never been an application that allows that type of collaboration. That's what Wiki software is for.
