Hello Joe,
I am sorry but currently EasySocial does not import avatars from Kunena currently
Does seem like a handy feature though. The kunena signature field allows your users to update their Kunena signature when they edit their profile in EasySocial and by doing so, this will slowly unify all the extensions that you use through EasySocial. This is a great hurdle for us because we have EasyBlog / EasyDiscuss where they all have their own profile settings. However, since EasySocial, we have created additional fields that would unify all these profile settings into one
As for the Kunena app, it actually displays the user's posts and replies in their profile
