I was going to download the latest server/client but looked like it hadn't been updated in awhile? Then I saw that the site had lost a years worth of data. Is there a link to the newest update somewhere?
Also, how ready is this engine? As in ready to start making a basic online RPG?
Follow this guide if you want the latest.

The engine includes a demo game which you can use. In it's current state, there isn't a wizard that will generate all the stuff you want. There are editors for everything but they are slightly hard to understand.
You will have to either code in what you want or use the very basic things that NetGore provides. That also includes sprites and animations.
