For security purposes, I can not disclose what Nimble is licensed for on this public support space. However, your community manager can invite you to the Nimble private support group where you will be able to ask the question.
Generally speaking though, because the site URL you provided ends with jiveon.com I know that it is a Cloud environment whereas the documentation you referenced is for a Hosted environment.
Enabling Events is slightly different for Cloud environments, in fact, Events is included in all of Essentials + and Enterprise versions. Events is not available however on the version of Essentials.
For the list of all the features included on each cloud version, please see Pricing - Jive Software.
Hope this helps.
How about pointing to the URL of that private support group? And maybe emailing me so I can invite him?
Thanks a lot,
Certainly, here is the URL for that specific group Nimble Storage - Employee. On the right side of the page you will see option to invite people to join this group, and just below that you will see an Environments Section which will provide you information on the Environment Type as well as version.
Let me know if this helps.
