I've had a bunch of people sign up for chitika.com under me, but they haven't received confirmation emails...how long has it taken for your referrals to get approved?
I've seen a 24 hour delay so far until the referrals are added to your account.. and nothing gets done over the weekend.. so I would say 2 to 3 days is not unusual.
Just a note. Sometimes the screens may say X number of referrals and the Active referrals may be blank. In reality blank is NOT equal to zero - just a bug in their system.
