Player Made Scenario questions

[zantsuken]

1) Do I edit and create my scenario on my local PC and then upload it to the Ryzom servers?

2) Is the data for the scenario stored on the Ryzom server? If I want to edit a scenario, do I need to download the data to my local PC and then push the edited files back?

3) Do I need to leave my PC logged into Ryzom for my scenario to be available in the Ring?

I'm sure I will think of more questions later, but these will get me started
