I missed the initial announcement, but just got back into NXT to get some Ardor. There's two months left, so it's not too late. The value should be the NXT + the value or ARDOR. I just still a little confused of how child chains and the I think FNX all works, not being able to really visualize it. Like when I have ARDOR, what's the function of the FNX. (I think that's what it's called.)
Someone should create a video that would make the concept really clear for those just hearing about the concept, else the terms could be hard to understand for anyone casually reading.
Ardor is a forging chain, boss chain over all the child chains. The boss Ardor chain will not have utility functions, its purpose is to oversee that the decentralized consensus is maintained in the network. Functions of boss chain are few: maintaining consensus with forging, sending Ardor between accounts.
You must hold NXT to October 12, 2016 to receive Ardor.

FNX is a default child chain. You must hold NXT to Q3 2017 to receive FNX.
Utility functions of child chains are: sending coins, arbitrary messages, asset exchange, voting, marketplace, coin shuffling, data cloud, something else I surely missed because there are too many. More utility functions will likely be added, you should check the Nxt client 1.10.1 in my sig, it's awesome. Apps are built around these utility functions of child chains.
