about paid subscription

[Eudemon]

i have few questions regarding paid subscription feature

1,if i choose primary group upon subscription, what if that member already in a primary group?

2,i use it as donation, but does paypal treat it as a donation?

3,i see there is a note under setting
"Note:
For subscriptions to be automatically updated for your users, you will need to setup a return URL for each of your payment methods. For all payment types, this return URL should be set as:
  •  http://kumakuni.com/subscriptions.php"
what do i need to do to this?

1. I believe it will make it their primary group, move their current primary group to secondary, and move their secondary group back to primary once the subscription ends.

2. I don't believe it does. You'd have to ask them.

3. You have to configure this in PayPal, you essentially have to tell PayPal that that's the IPN address to use for payment notifications, otherwise there's no way PayPal can tell the forum a payment went through.
