Can be added? When someone order subscription from IPB Cpanel so we get e-mail. This is usefull when there are manual transactions and need admin action!

Wouldn't it be better to have the admin approve all subscriptions in a similar fasion to the validation system? Even so, an e-mail might be a good idea.

I agree that an email receipt of some sort would be a good idea, showing fields that could be customized on what to show within the "email subscription receipt" (as you could call it) of what the person purchased, what their username is, the duration of the subscription, etc. A definite +1.

Wouldn't that be part of the "fire off a custom PHP file" thing that is integrated into the system?
