1. No subscription required to view posts
2, Subscription required to post. When a person goes to post I want the subscription page to open.
They will be notified to sign up to post, with a PayPal account (or sign up for a PayPal Account) to process a $4.95 (every 30 days) charge to their credit card. The charge will take place automatically every 30 days until the subscriber hits the cancel button in their Profile. Additionally, The subsriber has the first 30 days free (posting permitted) and can cancel before the 30 days lapse and no charge to their card..
Hopefully this mod will include an option to import subscription from the phpbb2 group subscription mod.
If it does then you could setup phpbb2 with the exisiting group subscription mod installed and then just upgrade.
No subscription required to view post
is simply a permissions setting ie permission to post would need to be set to Private and appropriate group subscriptions set and set view posts to Anyone.
The present mod would allow you to set the conditions in Q2 so I'd suspect this mod will allow the same.
Warning though Paypal charge per transaction so setting a monthy fee could work out quite expensive.
