Questions about playerworld hosting/billing/development

[upsilon]

Hi. I just recently (today) got my playerworld aproved, and have a question. Its not showing up in the RC menu. I was under the impression that you could work on the playerworld prior to paying for hosting, just not open it up to the public. Can i? I really have no idea what im doing at the moment, and was hoping this would be the way to get started without a) screwing up someone elses server while poking around, and b) shelling out 60-100 bucks on a fleeting fancy.

Could someone maybe explain to me the progression from the server not existing, to the server being in a state where developers can log on and start working on the server? So far its been approved on graal.net, and i have a project page for it.. but, outward appearances don't suggest to me that anything other than the graal.net page for it exists yet.
