There are also affiliate networks without associated payment gateways:

E.g.:
- Commission Junction
- LinkShare
- Google Affiliate Network

CBSubs also supports Post Affiliates Pro and iDevAf with plugins, but those won't help you finding affiliates, only managing them.

For CBSubs, ClickBank is mainly a payment gateway.
As with any new gateway, we can implement with a corresponding customer commitment
