BuddyPress.org

Hi
we are configuring a new buddypress installation and want to insert a process whereby the buddypress profile owner cannot view the first message in a new message trail until they have made a donation payment. (Outside of the bp environment the payment system will send an instant notification to the bp site when the donation has been made). So what we need to know is:

a) how to insert a block on the profile owner opening up the first message in a new message trail (instead incorporating a message and link to the payment site).

b) opening up the new message trail) once the payment notification has been received by the system. (The payment notification can be configured as required)

Aside from this one area bp configuration does pretty much everything we need so its been developed without the need for php expertise (which we dont have).

Many thanks in anticipation of any help.
