I have gone through and edited all the permissions for the user groups and subscriptions. I have created 2 different subscriptions and a user group for each one. Now, when I try to do a test registration....it doesn't take me to page where I have to pay. Can somebody please help me?

Do I have to request API credentials through Paypal?

Yes...I am discovering that this is not a default feature of vB. Is it possible to make it so new registering users can't see anything without becoming a paying member?

I uploaded the plugin and it still doesn't happen. I have created 2 different subscriptions and a user group for each one. I'm guessing this plugin makes them chooose one during registration before being able to view the forums. Also, I have the e-mail confirmation turned on...would that pose an issue? Do I need to change any of the other settings for this to work? All the forum viewing permissions are done. Thanks for the help.

OK...I turned off the e-mail verification and it worked. The only problem is....if the new member just clicks on the forum index link before choosing a subscription...they can bypass it. Is there any way to stop this?
