I wrote them 4-5 days ago offering them $25 in an advertiser test account (we are launching an ad network next week) for them to test us out.

Should they wish to continue, they have the option of only paying when a user sign up, setting a retargeting pixel (for remarketing campaigns), track their ROI, block non-performing publisher placements, only to run their ads, for example, between 20:45 to 20:59 and even on specific days.

Still no answer
