Your contact at Bidtellect will provide you with the DSP URL (http://dsp.bidtellect.com) as well as your user-name and initial password to log in with once the MSA or IO contract has been signed. You can change your password at any time in the Security section found user icon on the top right. If you have admin privileges, you can create additional users for your account and assign them Read and/or WRITE access to each log in down to the campaign level in the Manage User section found in the left navigation bar (full description here: Manage Users).
The Help section contains all of the resources to set up your account and run your campaigns effectively using Bidtellect’s Native Advertising nDSP platform, found in the left navigation bar. You are reading it right now so presumably found your way here successfully :)
