As you might know, we are working on a new template language that users will be able to change in the future. So, most of those wishes will be possible with this system because it is very flexible and allows you to build any interface or node-based application. Some features like social networking (e.g., add friend) will require new modules implemented in java, but this is still possible (although it is not top priority for the near future). Internationalization will certainly be added, and I hope this will happen soon (we are already discussing these details).
As Hugo said, we are focused on the template language now. We will try to add features as members of premium support ask for them. So if you personally want "Add Friends" or "Internationalization ", please let us know.
Sorry but I still don't understand. When you first go to a forum, initially you have no friends. My understanding is that you can add friends to your friend list. But what does this accomplish exactly?
