Best add-on I've seen for credits. Let me add to this that it took me a while to understand how it works but only because the add-on is deep, heavily configurable with a ton of options. Luckily the developer and the community using it is not only engaged and helpful but patient! Developer pushes out quick updates derived from the community feedback received, is open to considering areas of improvement and has solid integrity in keeping the code and feel best in class. GREAT community engagement add-on that works with third party add-ons and is just remarkably flexible. Great addition to any community site.
