On the website it mentions referral discounts as a feature that's available. I don't see it in the rules list in a default install, is that functionality in an extension?

I think that just refers to the ability to create referral discount codes, not how you actually track referrals and distribute them.

Oh just like "use my discount code at checkout"?

Yeah

Oh gotcha, I thought it was like "click my link and get a referral discount" 😛

Typically for that kind of stuff you'd use a third party like FriendBuy, but it would be cool to have an extension for it.

I have a vague memory of seeing something that handled that from somewhere, but it was like a year ago or more, and I can't find the same set of google keywords to get me anything that looks useful. I'll keep hunting and see what I can find. Thanks for clearing up the blurb on the website though, I thought I was going crazy when I couldn't find that functionality anywhere 😛
