I'll give you my words of advice...
Don't bother. You won't find any free servers to host an MMO.
Also, you're previous thread says you've never worked on a real project with DBPro. Not only is DBPro a terrible choice to create an MMO server/client with, but from what I can tell, you don't have any experience whatsoever with programming games in general, even in DBPro.
If you have no budget, then you won't be likely to succeed with an MMO anyways. It takes a team of many people, resources (such as money), a LOT of time, a LOT of patience, and much skill to successfully create an MMO.
Since you're looking for something to create for your first DBP project, look for a
Pong tutorial or even try and make it yourself. You can always ask for help in the Newcomers or DBP board.
Again- do NOT try to make an MMO for 'free' by yourself as a first project. You will only find disappointment.
