My project will be for building a site where subscribers can pay every month to buy art lessons.
I am using IP.Board 3.0.x for the forum, IP.Subscriptions for subscription payments, and IP.Content's Database feature to contain the lessons.
This mod/application needs to add these features with as few file edits as possible:

1.) Acquiring Credits.   Automatically give credits to a user when they subscribe and renew their subscription.  The number of credits varies depending on the subscription package they buy.
2.) Spending Credits . Allow users to spend their credits to gain access to content.  Credits will be used to buy access to individual records in IP.Content Databases.
3.) Profile Information. A new profile tab that shows number of available credits and links to all content they have purchased.
4.) ACP Mods. Some additions to the ACP to manage things.
