join pay to blog, multi-domains and supporter

Hello,

I want to finally setup my project and need accurate pieces of advice from wpmudev experts and users.

I have already setup wp 3.0.1 with multiDB, domain mapping, and a few other plugins such as pay-to-blog and supporter. I also intend to install multi-domain plugin.

The reason why I’ve installed both pay to blog and supporter is that I want new users to be able to start blogging at a low price, then be able to upgrade to more plugins, themes and performance whenever the time is right for them.

To start with pay to blog then upgrade with supporter seems logical to me. Do you have better suggestions ?

when a user upgrades to supporter, Is there a way to automatically cancel recurring payments engaged with pay to blog plugin, to avoid double payment ?

your insights will be most welcome.
