Thanks for your advice 3HMonkey, i am comfortable with replication and have since made about 60% of the system work on network. My guess would say it will be tested and finished by wens. 
Unreal makes things very easy and the system architecture is very clean making implementation very simple.
I agree, if you wish to make a in depth and complex MMO good programming and engineering skills are incredibly important. I understand that a lot of the people who download this system will be looking to learn from this as a resource so i have spent a lot of time trying to make my comments and structure very readable. Code/blueprints i always think is deeply personal, however i have done my best to make the system easy to add to. I intend to make some videos soon to show what i mean, but i will finish replication first.
