Group memberships: 50 groups per Microsoft .NET Passport account, including applications pending approval.

Storage space per Microsoft .NET Passport account: You are allotted a pre-set number of megabytes (MB) of content across all MSN Groups that you belong to with a single Microsoft .NET Passport sign-in name. As you add content to your groups, the amount of your available storage space decreases. For example, if you manage a group for your family, and are a member of three other groups, all the content you add to those four groups will be deducted from your pre-set storage limit.
