Don't you think it is too early as the $97 off code will expired in December 11th ?
Besides, I think 3 additional domains offer is more interesting.
I think it all depends. You know that there used to be a gentleman's agreement on the forums for everyone to have the same level of discounted code? I don't know how I feel about this but it's an interesting thought. :)
I've been thinking myself what's going to be the most fair and generous code to give out - 3 domains and $50 or 4 domains and $37. You'd think it would be the 4 domains, but there are a lot of people who'd think that 4 extra domains is overkill for them and that they'd never use them.

Btw, anyone has a tip on how to encourage someone who has subscribe with our code to refer someone else as I hope for second referral actually :P
I don't think any encouragement is necessary or appropriate. These people are here to do their own thing. If they want to pursue the affiliate program they can do so, but I think the main thing is for them to be successful in their web hosting. In my opinion, that's the best way to get secondaries: just make sure that everyone gets all the help they need to have a "Happy Hosting" experience. And a lot of that help can be provided here on the forums or on the wiki!
