Hey, I was on a vacation but i'm back!
1. We removed webmaster referral tab, instead - we suggested to use referral earnings log. Though, you couldn't see affiliate names there. But after some feedback, we decided to bring this possibility back (it's in progress).
2. We removed old modal windows due to several reasons:
- According to our internal tests, the new signup window has better performance in terms of CR in Firstbuys on most traffic (even though it reduces CR in the signups)
- There was abuse of old modal windows by different partners which caused us losing significant amount of money every month, that’s why we are not planning to re-enable them.
3. AffiliateId is a cookie parameter, which is set each time after the click, while UserId is your permanent Id (it's built in your default link).
