Confuse about Upload Quotas

Hi,

What is the default upload quotas for free level? Let’s say I only have one Pro upgrade level, if I want to set free level quotas to 100mb, and Pro upgraded level quotas to 1000mb. How do I setup these limitations?

Also, there is a WordPress setting for maximun upload size for multisite blogs, do I enter 1000mb for this setting?

Thanks

Thomas
