The Helpful Rating for the Knowledge Base is a great idea. However, why not take it to the next step and add a comment box for those users who want to provide context around their rating.
Agree with this 100% Our team has identified a need for open ended commenting that allows us to tie that feedback to contacts, so that we may follow up with email and other communication.
I totally agree. Given that this is a feature that Hubspot already have for your own Knowledgebase, it seems obvious that your customers would want it too! Please add this function.
