Editorial Comments can only be used by users who are using Nelio Content Premium. We created comments to ease the communication among the different members of a team involved in the creation of a single post. Therefore, it’s a functionality that, from our point of view, only makes sense if you’re using Nelio Content Premium. If you’re currently using the Free Version of Nelio Content, you won’t be able to use editorial comments.

I purchased Nelio Content Premium, but I Still Can’t Use Editorial Comments…
After purchasing Nelio Content Premium, you’ll receive an e-mail with a License Key. You have to add this License Key in the plugin to unlock the features that are only available to subscribers, including Editorial Comments.
