Aem community license required for local instances
I started to use community features on my local instances. I was following the adobe doc https://helpx.adobe.com/experience-manager/6-2/communities/using/deploy-communities.html created community site on author and followed the steps to publish it. It got published but I am not able to configure any users on publish instance. Attached a screenshot which shows an error when try to open groups/members from community consoles and the log file errors as below.

log file from publish instance:-

I have configured the following things on my local:-
- configured replication agents
- replicated the crypto key
- enabled tunnel service
- even checked for primary publisher configuration enabled or not. by default it's on.
notes:- I have only basic AEM 6.2 version(no hot fixes or feature packs).
Questions:-
1. Do I have to have separate community license(I have AEM6.2 license on my local) to get community features to work on my local instance?
2. Do I have to install any additional packages on top of basic aem6.2 version if we get the community license?
3. I followed some demo videos (Scott's Digital Community: May 2016 Ask the Community Experts ) related to communities sent by smacdonald2008. There were saying they will be having additional features in aem6.3 like email notifications and some social integration plugins and additional features. if this is the case can we get additional community packages for aem6.2 version(assuming community license for aem6.2,we don't have any plans of upgrading to aem6.3 for now). Could you please guide me where to find the actual differences for aem6.2 communities vs aem6.3 communities.
thanks
