The Destiny is specifically designed for test usage. You can test changes on the client, but you can also test ages, which are compatible with MOULa.
You can find everything you need to set up the client
here.
As Rhee said, we need the .age file of your age. The .prp files are not required. If you send us the file it may take up to one day until we have uploaded it (depending on when I take a look into my Emails). You have to send us the .age file everytime you make a change to it (e.g. adding a new page or changing the sequence prefix, ...). Basically, the server needs the same age file as you have. You may also take a look at the
already installed ages to make sure you use a unique name and prefix.
Also remeber that you can only test MOULa compatible ages, so if you are building with blender and pyPRP 1.x you first have to convert your age.
If you have any question, just ask.

EDIT: We also have a sub forum, which is only seen by Members of the Destiny, so if you want to test your age in a Multiplayer environment you can share your files there to test it with other players.
