I believe, ASP.NET Forums has its own Points System. I admit that they are also powered by Community Server. The intergration to Community-Credit is simple and straight forward like saying 1, 2, 3.
Step 1: Contact admin (at) Community-credit.com and the helpdesk should authorize the website aspiring to link with Community-Credit.
Step 2: Refer and Consume the webservices exposed to them as a followup action to (Step 1).
Thanks and Regards,
