NOAH uses the DotNetNuke (DNN) Evoq Basic CMS version 9.x as the platform for staff (AMS) and members (website, or CMS) to interface with NOAH. DNN Evoq is a popular CMS used by over 50,000 websites and has a marketplace of extensions that others have built that can be added for additional CMS functionality. If there is an extension you are interested in, please contact support and we will get you more information. There are several add-on modules that clients are already using covered in the next section.
If you want to validate the version of DNN your site is using, login to your website as an administrator so you see the black DNN menu on the left of the screen and mouse over the Evoq logo at the top left. This will show the version that your site is using.
More information about the version can be found here- https://www.dnnsoftware.com/docs/developers/product-versions.html
Note that there is a difference between the Evoq version and the underlying DNN platform version.
DNN also has more documentation that can be found here- http://www.dnnsoftware.com/docs/, and a community that can be found here- https://dnncommunity.org/forums, and you might try searching the web and YouTube for DNN specific questions.
